coastline, in the indicated locations during the next 48 hours.

For a depiction of areas at risk, please see the National Weather

Service Storm Surge Watch/Warning Graphic, available at

hurricanes.gov.

A Hurricane Watch means that hurricane conditions are possible

within the watch area. A watch is typically issued 48 hours

before the anticipated first occurrence of tropical-storm-force

winds, conditions that make outside preparations difficult or

dangerous.

A Tropical Storm Warning means that tropical storm conditions are

expected somewhere within the warning area within 36 hours.

A Tropical Storm Watch means that tropical storm conditions are

possible within the watch area, generally within 48 hours.

A Hurricane Warning may be required for portions of the Texas coast

later today or tonight.

inland watches and warnings, please monitor products issued by your

local National Weather Service forecast office.

DISCUSSION AND OUTLOOK

----------------------

At 1000 AM CDT (1500 UTC), the center of Tropical Storm Beta was

located near latitude 26.6 North, longitude 92.6 West. Beta is

moving toward the northwest near 3 mph (6 km/h). A slow westward

motion is expected to begin later today, with a slow northwestward

motion forecast to begin late Sunday or Sunday night and continue

through late Monday. On the forecast track, the center of Beta

will slowly approach the Texas coast into early next week.

Maximum sustained winds are near 60 mph (95 km/h) with higher gusts.

Little change in strength is expected today. After that, slow

strengthening is forecast, and Beta is expected to be at or near

hurricane strength Sunday night or Monday.

Tropical-storm-force winds extend outward up to 175 miles (280 km)

from the center.

The estimated minimum central pressure is 994 mb (29.36 inches).

HAZARDS AFFECTING LAND

----------------------

Key messages for Beta can be found in the Tropical Cyclone

Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC.

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 could

reach the following heights above ground somewhere in the indicated

areas if the peak surge occurs at the time of high tide...

Port Mansfield, TX to Cameron, LA including Baffin Bay, Corpus

Christi Bay, Copano Bay, Aransas Bay, San Antonio Bay, Matagorda

Bay, Galveston Bay, Sabine Lake, and Calcasieu Lake...2-4 ft

Mouth of the Rio Grande, TX to Port Mansfield, TX...1-3 ft

Cameron, LA to Ocean Springs, MS including Vermilion Bay...1-3 ft

Lake Maurepas, Lake Pontchartrain, and Lake Borgne...1-3 ft

The deepest water will occur along the immediate coast in areas of

onshore winds, where the surge will be accompanied by large and

dangerous 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 expected in the tropical storm

Warning area by late Sunday or Sunday night. Hurricane conditions

are possible within the hurricane watch area by late Monday or

Monday night. Tropical storm conditions are possible within the

tropical storm watch area along the southwestern Louisiana coast as

early as tonight. Tropical storm conditions are possible within

the tropical storm watch area along the south Texas coast Sunday

night

RAINFALL: Beta has the potential to produce a long-lived rainfall

event along the western Gulf Coast. Today through Tuesday, Beta is

expected to produce rainfall accumulations of 3 to 5 inches with

isolated totals of 10 inches beginning Saturday across southern

Louisiana and spreading into coastal Texas on Sunday. Flash and

urban flooding is likely as well as minor river flooding. Additional

heavy rainfall amounts across the western Gulf Coast are possible

through late week as Beta is expected to move slowly near the Texas

coast.

SURF: Swells are expected to increase and reach the coast of Texas

and the Gulf Coast of Mexico later today, generated by a combination

of Beta and a cold front entering the northern Gulf of Mexico.

These swells are likely to cause life-threatening surf and rip

current conditions. Please consult products from your local weather

office.
