DISCUSSION AND OUTLOOK
----------------------
At 1000 AM CDT (1500 UTC), the center of Tropical Storm Bertha was
located near latitude 29.6 North, longitude 93.2 West. Bertha is
moving toward the west near 10 mph (17 km/h) and this motion with
some increase in forward speed is expected during the next day or
so. On the forecast track, the center of Bertha will move near or
along the Louisiana and upper Texas coasts during the next several
hours, and then move inland over Texas this evening.

Maximum sustained winds remain 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 until it reaches the
upper Texas coast later today. The system is expected to dissipate
inland over Texas late tonight or Friday.

Tropical-storm-force winds extend outward up to 160 miles (260 km)
from the center.

The minimum central pressure based on data from the Air Force
Reserve reconnaissance aircraft is 1004 mb (29.65 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 Port Fourchon, LA...1-2 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
Thursday night 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 and northwestern Gulf Coast. These swells are
likely to cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.

A depiction of rip current risk for the United States can be found
