There are no coastal watches or warnings in effect.

There are no coastal watches or warnings in effect.

Key messages for Beta can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC.

RAINFALL: For the middle and upper Texas coast, additional rainfall of 4 to 8 inches with isolated storm totals up to 20 inches is expected. Significant flash and urban flooding is occurring and will continue today. Minor to isolated moderate river flooding is likely. Rainfall totals of 13 to 14 inches have been measured across portions of the Houston metropolitan area thus far.

Rainfall totals of 2 to 5 inches are expected east into the Lower Mississippi Valley and portions of the Tennessee Valley through the end of the week. Flash and urban flooding is possible, as well as isolated minor river flooding on smaller rivers.

TORNADOES: A tornado or two cannot be ruled out this evening along the upper Texas and southwestern Louisiana coasts.

SURF: Swells generated by a combination of Beta and a cold front over the northern Gulf of Mexico will continue along the coasts of Louisiana and Texas during the next couple of days. These swells are likely to cause lifethreatening surf and rip current conditions. Information on ongoing coastal flooding can be found in coastal flood products issued by local National Weather Service offices.

At 400 PM CDT (2100 UTC), the center of Tropical Depression Beta was located by surface observations, satellites, and NOAA Doppler weather radars near latitude 29.0 North, longitude 96.3 West. The depression is moving toward the eastnortheast near 5 mph (7 km/h) and this general motion is expected to continue through Friday. On the forecast track, the center of Beta will move inland over southeastern Texas through Wednesday and then over Louisiana and Mississippi Wednesday night through Friday.

Data from surface observations and NOAA Doppler weather radars indicate that maximum sustained winds have decreased to near 30 mph (45 km/h) with higher gusts. Gradual weakening is forecast through Friday, and Beta is expected to become a remnant low pressure system by late Wednesday.

The estimated minimum central pressure based on nearby surface observations is 1008 mb (29.77 inches).
