"THE HURRICANE OF AUGUST 31 TO SEPTEMBER 6, 1935
"By W. H. McDONALD
"[Weather Bureau, Washington, October 1935] "The full life history of the hurricane
that devastated some of the Florida Keys on the afternoon and night of
Labor Day, September 2, 1935, covers almost two weeks.
"The first indications of conditions
favorable to the origin of this disturbance were noted during the last
2 or 3 days of August, to the eastward and northward of Turks Islands;
but it was not until August 31 that a definite depression appeared, near
Long Island in the southeastern Bahamas, and deepened rapidly as it moved
westward. The identity of the disturbance can be clearly followed from
that region, over along path around Florida and across the South Atlantic
States to the forth Atlantic Ocean, where, off southern Greenland it was
lost on September 10 by merging with a cyclone of extratropical origin.
This path in its entirety is
shown on chart X.
"Hurricane intensity was doubtless
reached by the developing disturbance near the south end of Andros Island
on September I. Hurricane windy were last reported along the track on September
8 as the storm was moving northeastward over the Atlantic Ocean.
"The vortex was at the stage
of maximum violence, though still of small diameter, as it crossed the
Florida Keys between Key West and Miami, September 2, moving northwestward.
(See chart IX.) The central minimum barometer there was probably somewhat
below 27 inches, as indicated by readings of three aneroids on the gels,
the values ranging from 20.75 .to 26.98. Effort is being made to secure
one or more of these instruments for testing, because any authenticated
pressure value below 27 inches will constitute a new low record for the
Western Hemisphere.
"Attendant winds on September
2 were of phenomenal violence as is shown by physical effects almost equivalent
to those experienced m tornadoes. One observer reported his house partially
demolished by a wind-driven beam, 6 by 8 inches in section and 18 feet
long, which was blown 300 yards from another building; this occurred at
a tune nearly 3 hours in advance of arrival of the calm center. It was
this observer's impression that the winds were still more violent afterward.
The lenses and a 5/8 inch protecting glass of Alligator Reef Lighthouse,
135 feet above sea level, were reported to have been completely destroyed
by the hurricane; and it is unlikely that this destruction could have been
produced by flying debris.
"It seems safe to estimate
that winds of 150 to 200 miles per hour occurred near and over the Keys,
with gusts probably exceeding 200 miles per hour.
"Over a distance of about 30
miles, from the settlement of Tavernier (about 25°O1' N., 80°32'W.)
to Vaca Keys, one destruction of buildings, roads, viaducts, and bridges
was practically complete. Much of this damage was caused by the overwhelming
depth and strong washing flow of the storm tide that piled up on the Keys
under the driving power of the storm. The tracks of the Florida East Coast
Railroad were completely destroyed where they crossed between islands and
were shifted bodily off their roadbed over long stretches on the Keys.
An 11-car train, sent to Lower Matecumbe Key m an effort to rescue inhabitants,
was washed from the tracks and only tile locomotive withstood the force
of wind and tide.
"The disposition of debris
and nature of the erosion of the railroad embankments clearly indicate
that the destructive tide flowed with intense effect over the Keys from
southeast to northwest, in the direction of advance of the storm center.
"As is usually the case, the
destructive effects extended considerably farther to the right titan to
the left of the path of the center. Had there been no accompanying tide,
the damage undoubtedly would have been severe but by no means so complete
as that resulting from the tidal inundation. The track and crossties of
the railroad were in one stretch washed off a concrete viaduct 30 feet
above ordinary water level, but wave action superimposed on the tide no
doubt play tides part in this destruction. Reports agreed in the description
of the great rapidity with which the rise of the sea came in from the southern
side of the Keys as a "wall of water" or a "high wave."
"The Danish motorship Leise
Maersk was carried over Alligator Reef and grounded nearly 4 miles
beyond, after being totally disabled by the wind and sea, with engine room
flooded. Captain Richard Morthensen described the grounding as follows:
"Ship struck outer edge of Alligator Reef 9 o'clock (p. m.) and was carried
over the reef by a wall of water inland 3;4 miles through the northward
force of the wind, which was terrible." None of the crew was lost, though
all superstructures were wrecked. The ship was salvaged September 20.
"The American steamship Dixie
was also carried aground somewhat farther north, on French Reef, without
loss of life; this ship was refloated on September 19 and towed to New
York. The American tanker Pueblo drifted helplessly in the storm
from 2 to 10 p. m. of September 2; she went out of control near 24°40'
N., 80°25' W., and was carried completely around the storm center,
finding herself in 8 hours about 25 miles northeastward of her original
position,
and just barely able to claw off Molasses Reef as the force of the storm
began to abate. The lowest barometer reading on the Dixie was 27.28
inches (corrected), and on the Pueblo, 27.18 inches (uncorrected).
"The passage of the hurricane is
graphically described in a report submitted by J. E. Duane, cooperative
observer for the Weather Bureau and in charge of a fishing camp on Long
Key, over which the center passed. Extracts from his report follow, in
the chronological order of his observations:
"September 2: 2 p. m. - Barometer
falling; heavy sea swell and a high tide; heavy rain squalls continued.
Wind from N. or NNE'., force 6.
" 3 p. m. - Ocean swells had changed
this change noted was that large waves were rolling in from SE., somewhat
against winds which were still in N. or NE.
"4 p. m. - Wind still N.,
increasing to force 9. Barometer dropping 0.01 every 5 minutes. Rain continued.
"5 p. m. - Wind N., hurricane
force. Swells from SE.
"6 m. - Barometer 28.04;
still falling. Heavy rains. Wind still., hurricane force and increasing.
Water rising on north side of island.
"6:45 p.m. - Barometer
27.90. Wind backing to NW., increasing; plenty of flying timbers and heavy
timber, too - seemed it made no difference as to weight and size. A beam
6 by 8 inches, about 18 feet long, was blown from north side of camp, about
300 yards, through observer's house, wrecking it and nearly striking 3
persons. Water 3 feet from top of railroad grade, or about 16 feet.
"7 p. m. - We were now located
in main lodge building of camp; flying timbers had begun to wreck this
lodge, and it was shaking on every blast. Water had now reached level of
railway on north side of camp (ED. NOTE. - This was water rapidly
piled up from the shallow expanse of Florida Bay, under the drive of northerly
hurricane winds.)
"9 p m. - No signs of storm
letting up. Barometer still falling very fast.
"9:20 p. m - Barometer
27.22 inches; wind abated. We now heard other noises than the wind and
knew center of storm was over us. We now head for the last and only cottage
that I think can or will stand the blow due to arrive shortly. All hands,
20 in number, gather in this cottage During this lull the sky is clear
to northward, stars shining brightly and a very light breeze continued;
no flat calm. About the middle of the lull, which lasted a timed 55 minutes,
the sea began to lift up, it seemed, and rise very fast; this from ocean
side of camp. I put my flashlight out on sea and could see walls of water
which seemed many feet high. I had to race fast to regain entrance of cottage,
but water caught me waist deep, although writer was only about 60 feet
from doorway of cottage. Water lifted cottage from its foundations, and
it floated.
"10:10 p. m. - Barometer
now 27.02 inches; wind beginning to blow from SSW.
"10:15 p. m. - The first
blast from SSW., full force. House now breaking up - wind seemed stronger
than any time during storm. I glanced at barometer which read 26.98 inches,
dropped it in water and was blown outside into sea; got hung up in broken
fronds of cocoanut tree and hung on for dear life. I was then struck by
some object and knocked unconscious.
"September 3:
2:25 a. m. - I became conscious in tree and found I was lodged about 20
feet above ground. All water had disappeared from island; the cottage had
been blown back on the island, from whence the sea receded and left it
with all people safe.
"Hurricane winds continued
till 5 a. m. and during this period terrific lightning flashes were seen.
After 5 a. m. strong gales continued throughout day with very heavy rain."
"The wind lulled briefly between
8 and 9 p. m. at Alligator Reef, with direction shifting sharply from northeast
to southeast; this point was just at the northern edge of the calm center.
A calm of 40 minutes' duration was experienced on Lower Matecumbe Key;
and, as reported above, there was 55 minutes' respite at Long Key fishing
camp, but the wind changes at the latter point indicate that the geometric
center passed slightly to northward. It is somewhat difficult to reconcile
these reports with the general storm path. The rate of progression over
this section of the track was about 10 miles per hour, however, and from
this it is estimated that the calm center was perhaps 8 miles in diameter.
"The loss of life on the Keys
was very heavy, Three populous relief work camps inhabited by war veterans
were destroyed. The best estimate of mortalities, furnished by the American
Red Cross places the total at 409, of which number 244 are known dead and
165 missing.
"The rescue of survivors was
greatly hampered by lack of all means of communication. and transport;
but the Coast Guard promptly threw into the work 18 cutters, tugs, and
patrol boats, 5 amphibian planes, and other facilities. The Red Cross an
other public and private agencies of rescue were also promptly at work,
so that the aftermath of mortalities from injuries and lack of supplies,
was held to a minimum.
"After passing the Keys, the
hurricane moved slowly into a broad recurve northward, closely parallel
to the west coast of the Florida Peninsula, to pass inland, on the afternoon
of September 4, over the Gulf coast between
Apalachicola and Cedar Keys. The times of lowest barometer at various
places along the coast northward from Key West give a good indication of
the rate of
progress. At Everglade (on the west coast about opposite Miami)
the lowest barometer reading was 29.69 inches 6 a. m., September 3; at
Egmont Key (entrance to Tampa Bay), 28.94, 11 p m. of the 3d; and at Cedar
Keys, 29.08, 1:50 p. m. of the 4th.
"A slow increase in hurricane
area took place along this part of the path, coincident with a decrease
in central intensity, although the storm was still of hurricane force when
it passed inland. Considerable damage to buildings, docks, and fishing
craft occurred on the west coast, especially at Cedar Keys, and three lives
were lost.
"Northward along the west coast of
the peninsula the tides shifted from abnormally low stages produced by
the high offshore winds of the front quarter, to a heavy but not disastrous
rise as the onshore winds in the rear of the storm came into play. Tides
at many places on that coast rose 5 feet or more above normal, after the
passage of the trough line; and the town of Cedar Keys experienced the
highest tide and worst flooding since 1896.
"During September 5 the storm
moved from Georgia across the Carolinas, attended by high winds and heavy
rains that caused some damage to property and crops, especially in southern
Georgia. On the morning of September 6 the center of disturbance passed
again into the Atlantic near Cape Henry, Va., where the lowest barometer
was only 29.31 inches) showing that there had been a great decrease in
intensity of the storm during progress over the Atlantic coastal plain.
"The cyclone deepened again
on moving out to sea; and on the morning of September 7 the American steamer
Excelsior
recorded a barometer reading of 28.46 with a whole gale from the south,
shifting suddenly to storm force from the north, near 42° N., 54°
W. She central minimum continued below 29 inches for two days longer. The
American steamer Black Condor recorded 28.02 inches on the evening
of the 8th, near 51° N., 31° W.; and on the 9th the Danish
ship Frederick VIII recorded a reading of 28.73 inches near 55°
N., 35° W., a considerable distance from the center. The cyclone was
at that time diminishing in intensity and merging with another, so that
by the 10th it could no longer be distinguished from the cyclonic condition
commonly present at high latitudes in the North Atlantic Ocean.
"Winds of hurricane strength
were reported by a number of vessels along the track of this storm in the
North Atlantic; the first such report coining from the American steamship
Quirigua,
which encountered the rapidly deepening cyclone on the 6th when less than
100 miles off the Delaware coast. The last reports of hurricane winds came
from ships near mid-ocean, on the 8th.
"Total property losses entailed
by this hurricane are very difficult to estimate, but doubtless exceed
$6,000,000; practically all the loss was suffered in Florida, and most
of it over the Florida Keys.
"Warning service began on August
30, when the first strong indications of an incipient cyclone were noted
northward of Turks Islands. Warnings and advices followed at frequent intervals
thereafter, outlining the development and forecasting the progress of the
storm area, until the night of September 6, when the disturbance was moving
rapidly northeastward, well out in the Atlantic Ocean.
"During the developing stage of the hurricane,
as it was moving over remote islands and shoals of the southern Bahamas
where there were no ships or island stations to report the passage of tae
small vortex, the problems of accurately locating the center and its line
of advance and of forecasting its probable. movement were extremely difficult.
Nevertheless, daily and generally accurate advices were issued by the forecast
center at Jacksonville, Fla., during this period. Two examples from this
series of frequent advisory bulletins will illustrate their character:
"Jacksonville, Fla., September
1, 1935. - Advisory 9:30 a. m: Tropical disturbance central a short distance
south of Andros Island moving westward about 8 miles per hour attended
by shifting gales and probably winds of hurricane force over a small area
near the center. Indications that storm will pass through Florida Straits
late tonight or. Monday. Caution is advised vessels in path. Northeast
storm warnings displayed, Fort Pierce to Fort flyers.
"Jacksonville, Fla., September
2, 1935. - Advisory 3:30 a. m. Tropical disturbance still of small diameter
but considerable intensity is moving slowly westward off the coast of north
- central Cuba, attended by shifting hales and probable winds of hurricane
force over a small area. It will probably pass through the Florida Straits
Monday. Caution is advised against high tides and gales on the Florida
Keys and for ships in its path.
"The progress of the hurricane northward
and northeastward beyond the Florida Straits was fully covered by forecasts
and timely warnings issued in turn from the Jacksonville and the Washington
forecasting centers, as the storm moved from the one district into the
other." —————————————-
