The following information is based on satellite imagery, weather observations, radar and meteorological analysis. Based on 1200 UTC surface analysis and satellite imagery through 1715 UTC. ...SPECIAL FEATURES... Tropical Depression Beta is centered near 28.9N 96.7W at 22/01500 UTC or 13 nm ENE of Victoria Texas moving NE at 2 kt. Estimated minimum central pressure is 1005 mb. Maximum sustained wind speed is 30 kt with gusts to 40 kt. Scattered moderate convection extends out 150 nm from the center in the NE semicircle. A slow motion toward the east-northeast is expected by this afternoon and tonight. An east-northeastward to northeastward motion with increasing forward speed is expected Wednesday 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. Little change in strength is expected today with gradual weakening anticipated through Friday.

A tropical wave is located along 21W S of 16N, moving W at 10 to 15 kt. Scattered moderate convection is from 04N-07N between 20W-24W. A weak tropical wave extends along 33W S of 20N, moving W at 10 to 15 kt. No significant convection is occurring with this wave. ...MONSOON TROUGH/ITCZ... The monsoon trough extends from the coast of W Africa near 12N16W to 06N27W. Scattered showers are within 180 nm of the monsoon trough. GULF OF MEXICO... Please see the Special Features section above for further details on Tropical Depression Beta inland over Texas. As of 22/1500 UTC. A cold front has now stalled over the eastern and central Gulf from 22N80W to 30N94W. Scattered moderate convection is within 60 nm of the front. North of the front over the NE Gulf, strong NE winds prevail. These winds will gradually decrease to fresh later today and tonight. Gentle winds prevail over the remainder of the Gulf of Mexico south of the front. In the far western Gulf, gentle winds prevail south of 25.5N. Impacts from Beta will remain confined to nearshore coastal waters of Texas and Louisiana. A stationary front extending from the north-central Gulf to western Cuba will move back northward on Thursday through Saturday. Low pressure may form along this frontal boundary in the southeast Gulf later this week. CARIBBEAN SEA... Scattered moderate convection is Cuba due to the stationary front. Mainly fair weather conditions prevail elsewhere across the basin under the influence of mid level high supporting dry air subsidence. Scattered moderate convection S of 11N, along the Panama and Colombia coasts, is associated with the east Pacific monsoon trough. Gentle to moderate winds prevail. Swell associated with Teddy moving away in the north Atlantic as well as generated by a cold front currently extending along 22N-23N W of 61W will impact much of the Atlantic passages beginning tonight and continuing through at least Thu night. Mainly gentle to moderate trade winds will dominate the basin through the forecast period, with the exception of moderate to fresh winds near the coast of Colombia and in the Gulf of Venezuela. ATLANTIC OCEAN... A cold front extends from 31N58W to 24N64W to 22N80W. Scattered moderate convection is within 60 nm of the front. Strong NE winds area located to the N and W of the front, including the Bahamas. Ahead of the front, strong S winds are occurring N of 28N. A weak 1011 mb low near 14N51W is along a NE-SW surface trough that extends from 17N47W to 12N53W. Another surface trough is from 23N42W to 18N45W. A broad area of moderate, disorganized convection resides in the vicinity of these features from 11N-17N between 42W-48W. Swell generated by Teddy and a cold front that is slowing over the southeastern waters will continue to impact the waters through at least Thu night. In the wake of the front, high pressure building into the Mid-Atlantic U.S. will bring fresh to strong winds to areas N of the Bahamas and off the Florida coast into tonight. $$ Formosa
