Special Heavy Rainfall Report

...Rainfall total for July now almost 10
inches at Jamaica Beach...
A steady surge of highly moist and
unstable tropical air from the Gulf of
Mexico
interacting with various mesoscale and
synoptic-scale weather disturbances at
the
surface and in the upper atmosphere has
produced a deluge of rainfall since the
beginning of the month on Galveston
Island. Although only 5¼ days old, the
rainfall
total for July is now almost 10 inches
at the Jamaica Beach Weather
Observatory.
At one point this morning, rain was
falling so heavily in Jamaica Beach that
0.48 of
an inch of rain fell in a 5-minute
period...1.12 inches fell in a 15-minute
period...and
2.00 inches fell in a 1-hour period.
The following 24-hour daily rainfall
totals were recorded at the Jamaica
Beach
Weather Observatory each day
from Midnight to Midnight CST (1AM to
1AM CDT):
July
1................... 2.06"
July
2................... 0.12"
July
3................... 3.75"
July
4................... 1.24"
July
5................... 0.69"
July 6 (thru
6AM CST).... 2.04"
------------------------------
STORM TOTAL SO
FAR....... 9.90"
The record monthly total for the month
of July at Jamaica Beach is 10.38 inches
which occurred in July 2003. With more
heavy rain expected, it is very possible
that a new monthly record for the month
of July will be set later today. The
record
monthly total for any month at Jamaica
Beach is 18.23 inches which occurred in
September 2002...a year that also saw
the greatest annual total ever recorded
at
this station when an incredible 80.25
inches of rain fell that year. Both of
these
dubious records appear to be in no
danger of being broken anytime soon.
Although the eastern half of Galveston
Island has also seen its share of heavy
rainfall during the past several days,
substantially less rain has fallen at
Scholes
International Airport in Galveston than
at Jamaica Beach. The comparison of day
to day rainfall totals at these two
official National Weather Service
reporting
stations illustrate quite well the wide
variance in precipitation distribution
that
often occurs on this 32-mile long
barrier island along the Texas Gulf
Coast.
The following
24-hour daily rainfall totals were
recorded at Scholes International
Airport in
Galveston each day from Midnight to
Midnight CST (1AM to 1AM CDT):
July 1................... 0.44"
July 2................... 0.03"
July 3................... 2.86"
July 4................... 0.64"
July 5................... 1.80"
July 6 (thru 6AM CST).... 0.31"
------------------------------
STORM TOTAL SO FAR....... 6.08"
Further updates
on this continuing heavy rainfall
event will be issued as necessary.
