Based on 0600 UTC surface analysis and satellite imagery through 1015 UTC. ...SPECIAL FEATURES... Tropical Depression Nineteen is centered near 28.9N 50.2W at 06/0900 UTC or about 780 nm E of Bermuda and about 1275 nm WSW of the Azores moving E at 5 kt.

See the latest NHC Forecast/Advisory under AWIPS/WMO headers MIATCMAT4/WTNT24 KNHC for more details. ...ITCZ/MONSOON TROUGH... The monsoon trough extends from the African coast near 12N16W to 09N20W. The Intertropical Convergence Zone axis extends from 09N20W to 04N36W to 01N50W. Isolated moderate convection is from 01N-07N between the Prime Meridian and 10W...and from 04N-12N between 10W-21W. Scattered moderate convection is from 01N-09N between 21W-45W. ...DISCUSSION... GULF OF MEXICO... A surface ridge anchored by a 1020 mb high centered near 29N86W continues to prevail across the entire basin this morning. Latest scatterometer...ship...and buoy data indicates gentle to moderate anticyclonic flow throughout...with occasional fresh southerly winds across the far NW waters. The ridge is expected to move little and remain nearly stationary across the NE Gulf waters through Tuesday night. Moderate to occasional fresh southerly return flow is forecast across western portions through Wednesday as the next front is expected to emerge off the Texas and Louisiana coast Wednesday afternoon into the early evening. CARIBBEAN SEA... A middle to upper level trough with axis extending from over central Cuba to a base over NE Honduras near 16N85W is supporting scattered showers and isolated tstms east of the trough axis from 15N-21N between 73W-80W. Other isolated showers and tstms are occurring S of 14N between 68W-82W within southwesterly flow aloft. Farther east...shallow isolated showers are occurring primarily E of 72W...including Hispaniola...Puerto Rico...and several of the Lesser Antilles. Otherwise...gentle to moderate trades are expected to persist through Wednesday. ...HISPANIOLA... Isolated showers linger across the island this morning...as a middle to upper level trough lies to the W over the western Caribbean. The troughing is generating an area of divergence over the region within southwesterly flow aloft and generating widely scattered showers and isolated tstms across a large portion of the adjacent coastal waters from 16N-23N between 66W-76W. Gentle to moderate trades prevail at the surface. ATLANTIC OCEAN... Water vapor imagery indicates a middle to upper level trough with axis extending from 32N69W to over central Cuba to a base over Central America near 16N85W. This troughing supports a surface trough analyzed from a weak 1016 mb low near 26N80W to 30N76W. Maximum middle to upper level divergence associated with the troughing aloft is generating an area of widely scattered showers and isolated tstms from 19N-26N between 63W-75W. Across the central Atlc...Tropical Depression Nineteen is highlighted above. The remainder of the eastern Atlc is under the influence of a surface ridge with axis extending from 32N35W to 22N43W.
