000 AXNT20 KNHC 070524 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 124 AM EDT Thu Jun 7 2018 Tropical Weather Discussion for North America, Central America Gulf of Mexico, Caribbean Sea, northern sections of South America, and Atlantic Ocean to the African coast from the Equator to 32N. The following information is based on satellite imagery, weather observations, radar and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0515 UTC. ...TROPICAL WAVES... An Atlantic Ocean tropical wave extends its axis along 23W and south of 12N, moving west at 10-15 kt. Scattered moderate convection is noted from 05N-10N between 21W-28W. An Atlantic Ocean tropical wave axis is along 47W from 12N southward, moving westward 10 to 15 kt. No convection is observed at this time with this feature. A Caribbean Sea tropical wave axis extends from 18N73W to 11N75W, moving westward 15 kt. No significant convective precipitation is apparent in satellite imagery due to Saharan dust present in the wave's environment. A tropical wave extends over the Yucatan Peninsula along 91W, moving westward at 10 kt. Scattered moderate convection is observed along the wave's axis mainly south of 19N. ...MONSOON TROUGH/ITCZ... The monsoon trough extends from 10N13W to 06N22W. The ITCZ is along 05N27W to 04N45W. Scattered showers are noted along the ITCZ between 27W-30W. ...DISCUSSION... GULF OF MEXICO... A stationary front extends across the northeastern portion of the basin from 29N94W to 28N83W. Scattered showers cover the eastern Gulf waters in the vicinity of the front mainly east of 83W. Another area of scattered showers is noted over the Straits of Florida. THe tropical wave moving over the Yucatan Peninsula is enhancing convection inland mainly south of 18N. An upper-level trough extends from the NE corner of the basin along 87W-88W reaching the northern coast of the Yucatan Peninsula. The stationary front across the NE Gulf will dissipate overnight. A surface trough will develop along the Yucatan Peninsula each afternoon, and then drift westward in the the SW Gulf at night. CARIBBEAN SEA... An upper-level trough extends from the NE corner of the Gulf of Mexico into the Yucatan Peninsula. Broad upper-level anticyclonic wind flow spans the rest of the Caribbean, to the east of the trough. Scattered showers are noted over the western half of the basin mainly west of 73W. The monsoon trough is along 10N from NW Colombia westward, beyond NW Costa Rica. At this time, scattered showers are along this boundary affecting Panama and Costa Rica. Fresh to strong trade winds will persist in the central Caribbean. The wind speeds will be near-gale force, at night, near Colombia and Venezuela through the weekend. Fresh to strong winds are expected in the Gulf of Honduras through Saturday night. Moderate to fresh trade winds will prevail elsewhere through Sunday. ATLANTIC OCEAN... A stationary front extends across the west Atlantic from 28N80W to 31N72W. Abundant moisture is streaming northeastward, on the eastern side of the NE Gulf of Mexico-to-Yucatan Peninsula upper level trough. With these, scattered moderate convection is observed over the northern Bahamas mainly south of the front. The remainder of the basin is under the influence of a surface ridge, anchored by a 1026 mb high centered near 32N24W. The stationary front will weaken overnight. The broad ridge across the east-central Atlantic will dominate the regional weather through the weekend. For additional information please visit http://www.hurricanes.gov/marine $$ ERA
