indicated locations. For a depiction of areas at risk, please see
the National Weather Service Storm Surge Watch/Warning Graphic,
available at hurricanes.gov. This is a life-threatening situation.

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 400 PM CDT (2100 UTC), the center of Tropical Storm Harvey was
located by Doppler radar near latitude 29.1 North, longitude 97.6
West. Harvey has been nearly stationary and little motion is
anticipated during the next few days.

Maximum sustained winds have decreased to near 65 mph (100 km/h)
with higher gusts. Additional weakening is expected during the
next day or two.

Tropical-storm-force winds extend outward up to 115 miles (185 km)
from the center.

The estimated minimum central pressure is 990 mb (29.24 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL: Harvey is expected to produce additional rain
accumulations of 15 to 25 inches over the middle and upper Texas
coast through Thursday. Isolated storm totals may reach around 40
inches in this area. Elsewhere during the same period, Harvey is
expected to produce total rain accumulations of 5 to 15 inches
farther south toward the lower Texas coast, farther west toward the
Texas Hill Country and southwest and central Louisiana. Rainfall of
this magnitude will cause catastrophic and life-threatening
flooding. A list of rainfall observations compiled by the NOAA
Weather Prediction Center can be found at:
www.wpc.ncep.noaa.gov/discussions/nfdscc1.html

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

Port Aransas to Sargent...4 to 7 ft
Sargent to High Island including Galveston Bay...2 to 4 ft
High Island to Morgan City...1 to 2 ft

The deepest water will occur along the immediate coast near the
area of onshore winds, where the surge will be accompanied by large
and destructive waves. 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.

WIND: Tropical storm conditions are occurring in portions of
the tropical storm warning area, and are likely to persist along
portions of the coast through at least Sunday.

SURF: Swells generated by Harvey are affecting the Texas,
Louisiana, and northeast Mexico coasts. These swells are likely to
cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.

TORNADOES: A few tornadoes are possible through Monday near the
middle and upper Texas coast into far southwest Louisiana.
