Activity for July: 3 tropical storms

Atlantic Tropical Activity for July
-----------------------------------
July of 2005 was the most active month of July on record in terms of
number of named storms, intense hurricanes and net tropical cyclone
activity (NTC). Five tropical storms formed during the month, besting
the previous record of four set on several occasions (1966, 1995 and
1997). Two Category 3 hurricanes occurred in July of 1916, but this
year saw two Category 4 hurricanes form during the month, and strong
ones at that. Emily was on the threshold of Category 5 intensity at
its peak. The record number of hurricanes for the month of July is
three, set in 1966, so this year did not set a new record for that
parameter. The previous high NTC for July was 25.9% in 1996, with
July of 1966 coming in second with 24.1%. The NTC for July, 2005, was
63.5%, more than the previous two most active July's combined.
Of the five tropical cyclones which formed in July, four made land-
fall in either the U. S. or Mexico. Only Tropical Storm Franklin failed
to make a continental landfall, but even it crossed part of Great Abaco
Island in the Bahamas. Tropical Storm Cindy made landfall over south-
eastern Louisiana and again in extreme southwestern Mississippi. Major
Hurricane Dennis made two Category 4 landfalls in Cuba and eventually
struck the Florida Panhandle as a Category 3 hurricane. Mighty Hurricane
Emily struck Grenada as a Category 1 hurricane, the eastern Yucatan
Peninsula coastline as a Category 4 storm, and northeastern Mexico as
a Category 3 hurricane. Minor Tropical Storm Gert, much like June's
Tropical Storm Bret, formed in the Bay of Campeche and moved inland
into Mexico's Gulf Coast as a relatively weak tropical storm.
Reports on all five storms follow.
TROPICAL STORM CINDY
(TC-03)
3 - 8 July
----------------------------------------
A. Introduction and Storm Origins
---------------------------------
Right on the heels of an above-normal June, the most active July on
record in the Atlantic basin began to get underway early in the month.
Tropical Storm Cindy was the earliest third tropical storm of the season
to form since Tropical Storm Candy formed on 23 June 1968. The cyclone
formed in the Yucatan Peninsula region and followed a northerly path
across the Gulf of Mexico, making landfall in southeastern Louisiana
as a strong tropical storm just shy of hurricane intensity.
As early as 30 June a Tropical Weather Outlook issued by TPC/NHC
noted that a large area of cloudiness and thunderstorms associated with
a westward-moving tropical wave and a weak surface trough was present
over the central and southwestern Caribbean Sea. Upper-level winds
gradually became more favorable for tropical cyclogenesis over the next
couple of days, and by 2 July the disturbance was becoming better
organized about midway between the Cayman Islands and Honduras. By
midday on 3 July a broad area of low pressure had formed about 130 nm
east of Chetumal, Mexico.
The Hurricane Hunters flew a reconnaissance plane into the system
during the afternoon and found a closed circulation just east of the
Yucatan Peninsula. Even though deep convection had weakened some during
the day, there was still enough organization to warrant classifying the
system as a tropical depression. The first advisory on Tropical Depres-
sion 03 was issued at 2100 UTC and placed the center about 70 nm east
of Chetumal, or approximately 125 nm south of Cozumel.
B. Synoptic History
-------------------
During the evening hours of 3 July a strong convective burst erupted
over the LLCC with a reconnaissance plane indicating a CP of 1007 mb--a
drop of 2 mb in 2.5 hours. Also, significant banding had developed to
the east and north of the center. The depression was almost at tropical
storm strength as it began to move inland along the eastern Yucatan
coastline around 04/0600 UTC south of Cozumel. As expected TD-03 became
rather disorganized while over the Yucatan Peninsula with the circulation
elongating in a north-south direction. During the afternoon of 4 July
a new center apparently began reforming over the southern Gulf of Mexico.
During an early afternoon flight the Hurricane Hunters were unable to
close off a center, but it was assumed that a new center was forming in
the area where pressures were lowest. The 04/2100 UTC advisory placed
the developing new LLCC over the Gulf to the north of the Yucatan coast-
line and about 375 nm south of the mouth of the Mississippi River.
Following the development of the new LLCC over the south-central Gulf
of Mexico, the depression followed an initial north-northwesterly track
across the Gulf, becoming northerly early on 5 July as it reached
tropical storm intensity. The primary guiding influence was a deep-layer
ridge over the Florida Peninsula and the adjacent western Atlantic. The
outer convective banding features gradually improved during the night of
4-5 July as TD-03 marched across the Gulf of Mexico at about 11 kts. The
depression was upgraded to Tropical Storm Cindy at 0900 UTC on 5 July
while centered approximately 220 nm south-southwest of the mouth of the
Mississippi River. The upgrade was based on data from a reconnaissance
plane which found FLWs of 45-50 kts within a convective band east of the
center along with a CP of 1002 mb.
As Tropical Storm Cindy plowed onward toward the Louisiana coast it
continued to strengthen. The peak intensity of 60 kts was attained at
05/2100 UTC. The Stepped-Frequency Radiometer instrument on board a
NOAA Hurricane Hunter aircraft reported a few spot surface wind estimates
of 64 kts; however, the aircraft crew indicated that these speeds were a
little too high. As Cindy neared the coastline a burst of deep
convection developed over the LLCC and briefly wrapped up an eye-like
feature for about an hour, and reconnaissance reports indicated that the
CP had dropped to 992 mb. Reports from an offshore oil rig indicated
gusts to 86 kts at 45.7 metres above the surface at 2300 UTC. However,
after this time the radar signature became less distinct and the CP rose
back to 997 mb. Thus, Cindy almost became a hurricane shortly before
making landfall just west of Grand Isle, Louisiana, around 0400 UTC on
6 July.
By the time Cindy made landfall it had turned to a north-northeasterly
trajectory, which became more northeasterly with time. The cyclone had
weakened only slightly from its peak intensity when it passed just south-
east of New Orleans. Cindy's center moved briefly over water again as
it crossed Lake Borgne, then back inland along the Mississippi coastline.
Once inland the storm began to weaken rapidly and was downgraded to a
tropical depression at 06/1500 UTC when centered near the Mississippi-
Alabama state line approximately 80 km northwest of Mobile, Alabama.
At this time TPC/NHC relinquished the system to HPC for the purpose of
issuing advisories. HPC tracked the weakening cyclone northeastward
across central Alabama, northwestern Georgia, North Carolina, Virginia
and Maryland before the center moved into the Atlantic around 1500 UTC
on 8 July. The final HPC advisory at 08/2100 UTC placed the remnants of
Cindy about 50 nm northeast of Cape May, New Jersey, moving northeast-
ward at about 16 kts.

C. Meteorological Observations
------------------------------
The city of New Orleans (the town, not the train) experienced wind
gusts of 45-60 kts from Cindy. Some 200,000 persons in the metropolitan
area and in areas farther east lost power, some for two nights.
Following are storm rainfall totals gleaned from a comprehensive
file sent to the author by David Roth of HPC. (A special thanks to
David for sending the information.) The data are grouped by state,
and a number plus a compass direction, e.g., 10NW, means that the
observation was made 10 statute miles northwest of the given
location. Only storm totals >= 100 mm (3.94 inches) are given.

D. Damage and Casualties
------------------------
Wind damage from Cindy was rather minor and typical of a strong
tropical storm. Probably there was some damage from localized flooding,
but assessments are not complete at this time and estimates are not yet
available.
