7 AM Tropical Storm Bill Update | Slightly Stronger as it approaches Landfall

090804W_NL_sm

At 7 AM CDT Tropical Storm Bill was located 30 miles east/southeast of Port O'Connor or 105 miles southwest of Galveston. Movement is to the northwest at 13 MPH and we should have landfall within the next 3 hours. Maximum sustained winds have increased to 60 MPH in a small section of the storm. Our forecast and thinking has not changed since our 4 AM discussion. I'll share it again with you here for those who may have missed it.

The latest rain total forecast through Friday Morning depicts a dangerous situation for parts of Southeast Texas, Central Texas, and North Texas. Compared to yesterday we have seen a ~50 mile shift west in the projected track of Bill. The result is that the heaviest rains are now forecast to fall literally on Interstate 35 from Austin north into Oklahoma including the D/FW Metroplex. Widespread rain totals of 4 to 8 inches are likely with isolated totals up to 1 foot in some locations. That kind of rain in only a day or two will result in the threat for dangerous and widespread flash flooding. Rapid rises on local streams and creeks will be probable in the hardest hit areas. Rivers will quickly rise back into flood stage and some local lakes will once again be dealing with ridiculously high to record high levels. The lake and river flooding will persist well into next week even after the rains have stopped. As always I want to stress that not everyone will see the very heavy rains, not everyone will see flooding, not everyone will see the significant flooding. However I do believe we will have some locations hard hit by this system. Bill will be remembered for the flooding it produces - no question about it. Don't be afraid about it or get yourself into a panic. Stay up to date with your local weather conditions and if a flash flood warning is issued move to higher ground if needed. Listen to local emergency management announcements and follow their directions.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area.

For storm information specific to your area, including possible
inland watches and warnings, please monitor products issued by your
local National Weather Service forecast office.


DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 700 AM CDT (1200 UTC), the center of Tropical Storm Bill was
located near latitude 28.2 North, longitude 96.0 West. Bill is
moving toward the northwest near 13 mph (20 km/h) and this general
motion is expected to continue today.  On the forecast track, the
center of Bill is expected to make landfall in the warning area
along the Texas coast later this morning and move inland over
south-central Texas this afternoon and tonight.

Reports from an Air Force Reserve reconnaissance aircraft indicate
that maximum sustained winds have increased to near 60 mph (95 km/h)
with higher gusts. Little additional strengthening is expected
before landfall occurs in a few hours. Weakening is forecast after
the center moves inland later today, and Bill is expected to weaken
to a tropical depression tonight.

Tropical-storm-force winds extend outward up to 150 miles (240 km)
from the center.  During the past hour, a WeatherFlow observing
station at Matagorda Bay reported a wind gust to 45 mph (72 km/h).

The estimated minimum central pressure based on reconnaissance
data is 997 mb (29.44 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL:  Bill is expected to produce total rain accumulations of
4 to 8 inches over eastern Texas and eastern Oklahoma and 2 to 4
inches over western Arkansas and southern Missouri, with possible
isolated maximum amounts of 12 inches in eastern Texas.

WIND:  Tropical storm conditions are expected to reach the coast
within the warning area within the next hour or two.

STORM SURGE:  The combination of a storm surge and the tide will
cause normally dry areas near the coast to be flooded by rising
waters.  The water could reach the following heights above ground if
the peak surge occurs at the time of high tide...

Upper Texas coast...2 to 4 feet
Western Louisiana coast...1 to 2 feet

The deepest water will occur along the immediate coast near and to
the right of the landfall location.  Surge-related flooding depends
on the relative timing of the surge and the tidal cycle, and can
vary greatly over short distances.  For information specific to your
area, please see products issued by your local National Weather
Service forecast office.

TORNADOES:  A few tornadoes will be possible across portions of
eastern Texas and far western Louisiana today and tonight.
