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

For storm information specific to your area in the United States, including possible inland watches and warnings, please monitor

products issued by your local National Weather Service forecast office. For storm information specific to your area outside of the

DISCUSSION AND OUTLOOK ----------------------

At 100 PM CDT (1800 UTC), the center of Tropical Storm Alberto was located near latitude 22.2 North, longitude 95.1 West. Alberto is

moving toward the west near 9 mph (15 km/h). A westward motion with an increase in forward speed is expected through Thursday. On the

forecast track, the center of Alberto will reach the coast of northeastern Mexico early Thursday morning.

Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Some slight strengthening is forecast today or tonight before

the center of Alberto reaches land. Rapid weakening is expected once the center moves inland, and Alberto is likely to dissipate

over Mexico Thursday or Thursday night. Alberto is a large tropical storm, with tropical-storm-force winds

extending outward up to 415 miles (665 km) north of the center. The estimated minimum central pressure is 995 mb (29.39 inches).

HAZARDS AFFECTING LAND ----------------------

Key messages for Alberto can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT1 and WMO header WTNT41 KNHC.

RAINFALL: Tropical Storm Alberto is expected to produce rainfall totals of 5 to 10 inches across northeast Mexico into South Texas.

Maximum totals around 20 inches are possible across the higher terrain of the Mexican states of Coahuila, Nuevo Leon, and

Tamaulipas. This rainfall will likely produce considerable flash and urban flooding along with new and renewed river flooding. Mudslides

are also possible in areas of higher terrain across northeast Mexico.

For a complete depiction of forecast rainfall and flash flooding associated with Alberto, please see the National Weather Service

Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at1.shtml?rainqpf and the Flash Flood Risk

graphic at hurricanes.gov/graphics_at1.shtml?ero 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...

Sargent, TX to Sabine Pass, TX...2-4 ft Galveston Bay...2-4 ft

Mouth of the Rio Grande, TX to Sargent, TX...1-3 ft Sabine Pass, TX to Vermilion/Cameron Parish Line, LA...1-3 ft

The deepest water will occur along the immediate coast near and to the north of the landfall location, 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. 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_at1.shtml?peakSurge.

Storm surge will raise water levels by as much as 1 to 3 feet above normal tide levels along the immediate coast of northeastern

Mexico in areas of onshore winds north of where the center makes landfall. Near the coast, the surge will be accompanied by large

and destructive waves. WIND: Tropical storm conditions are expected within the warning

area today through early Thursday. TORNADOES: A couple of tornadoes are possible today and tonight

across parts of Deep South Texas and Southeast Texas. SURF: Swells generated by Alberto will affect the coast of Texas

and northeastern Mexico through Friday. These swells are likely to cause life-threatening surf and rip current conditions.
