Kyle was a small, short-lived tropical storm that formed over the northwestern Caribbean Sea in mid-October. It moved onshore near the border of Guatemala and Honduras as a weakening tropical depression and quickly dissipated. There were no significant effects on land associated with this system.
a. Synoptic History
Satellite imagery and rawinsonde data show that a tropical
wave moved off the west coast of Africa on 27 September. The wave was
tracked in satellite imagery to the Lesser Antilles on 5 October and to
the western Caribbean Sea on the 9th where it interacted with a frontal
cloud band. Surface analysis indicated a broad 1010 mb low over the northwest
Caribbean Sea at 0000 UTC 11 October. At this time, anticyclonic flow
aloft was seen in animation of satellite imagery above disorganized convective
A well-defined convective cloud band developed and post-analysis
suggests that a tropical depression formed from the disturbance near 1200
UTC 11 October while centered about midway between Swan Island and the
coast of Belize. Steering currents were weak and the depression began
drifting toward the southwest.
The tropical cyclone quickly intensified and is estimated
to have become a tropical storm at 1800 UTC on the 11th. A small central
dense overcast was evident in satellite imagery by the time the first
reconnaissance aircraft investigated the cyclone during the afternoon.
Maximum sustained surface winds of 52 mph are estimated to have occurred
from 1800 UTC on the 11th to 0000 UTC on the 12th. The minimum central
pressure of 1001 mb occurred near this time.
Upper-level southwesterly shear soon increased, resulting
in a decrease of the deep convection. It is estimated that Kyle weakened
to a tropical depression by 1200 UTC 12 October. The center of the rapidly
dissipating depression moved onshore near the border between Guatemala
and Honduras six hours later.
b. Meteorological Statistics
The limited aircraft data on 11 October were supplied by
the Hurricane Hunters of the U.S. Air Force Reserves. The satellite estimates
were provided by the NESDIS Synoptic Analysis Branch, the TPC's Tropical
Analysis and Forecast Branch and the Air Force Global Weather Center.
The maximum wind speed recorded from aircraft in Kyle was
56 mph from a flight level of 1500 feet at 1908 UTC 11 October. The minimum
observed central pressure was 1001 mb at 2145 UTC on the 11th, and was
extrapolated from 1500 feet.
Satellite estimates never exceeded T2.5 (40 mph) on the Dvorak
c. Casualty and Damage Statistics
No reports of casualties or damages were received by the NHC.
