DISCUSSION AND OUTLOOK
----------------------
At 400 AM CDT (0900 UTC), the center of Tropical Storm Bertha was 
located near latitude 29.0 North, longitude 92.2 West. Bertha is 
moving toward the west near 13 mph (20 km/h).  A generally westward 
or west-northwestward motion is expected through tonight, followed 
by a turn toward the west-southwest on Friday.  On the forecast 
track, the center of Bertha will move near or along the Louisiana 
and upper Texas coasts through this afternoon, and then move farther 
inland into Texas this evening and tonight.
 
Maximum sustained winds are near 45 mph (75 km/h) with higher gusts.
Little change in strength is expected today, and Bertha is forecast 
to maintain tropical storm intensity up until it reaches the upper 
Texas coast later today.  Bertha is expected to dissipate inland 
over Texas by tonight or Friday.
 
Tropical-storm-force winds extend outward up to 160 miles (260 km)
mainly to the southeast of the center.  The National Ocean Service 
station at Eugene Island, Louisiana, recently reported sustained 
winds of 39 mph (62 km/h) with a wind gust of 47 mph (76 km/h). An 
oil platform southeast of the center of Bertha recently reported 
sustained winds of 56 mph (90 km/h) at an elevation of 102 ft    
(31 m).
 
The estimated minimum central pressure is 1003 mb (29.62 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
Key messages for Tropical Storm Bertha can be found in the Tropical
Cyclone Discussion under AWIPS header MIATCDAT2 and WMO header
WTNT42 KNHC.
 
WIND:  Tropical storm conditions will continue spreading across
portions of the northern and northwestern Gulf Coast within the
warning area through today.
 
STORM SURGE:  The combination of storm surge and the tide will
cause normally dry areas near the immediate coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...
 
Port Bolivar, TX to Mouth of the Mississippi River, LA...1-3 ft
 
The deepest water will occur along the immediate coast.
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.
 
For a complete depiction of areas at risk of storm surge inundation,
please see the National Weather Service Peak Storm Surge Graphic,
available at hurricanes.gov/graphics_at2.shtml?peakSurge.
 
RAINFALL: Bertha is expected to produce total rainfall amounts of 2 
to 4 inches with isolated totals to 6 inches through tonight along 
Texas Gulf Coast and South Texas. This rainfall may produce isolated 
flash flooding, especially in urban areas.

For a complete depiction of forecast rainfall associated with 
Bertha, please see the National Weather Service Storm Total Rainfall 
Graphic available at hurricanes.gov/graphics_at2.shtml?rainqpf and 
the Flash Flood Risk graphic at 
hurricanes.gov/graphics_at2.shtml?ero.
 
SURF: Swells generated by Bertha will continue spreading westward
along the northern Gulf Coast during the next few days. These swells
are likely to cause life-threatening surf and rip current
conditions. Please consult products from your local weather office.
