000 AXNT20 KNHC 280007 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 2323 UTC Sat Jun 27 2020 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 1800 UTC surface analysis and satellite imagery through 2345 UTC. ...TROPICAL WAVES... A tropical wave moving off the coast of Africa extends from 03N-20N with axis near 17W, moving westward at 10-15 kt. Scattered moderate convection is from 05N to 11N E of 20W. A tropical wave extends from 02N-18N with axis near 40W, moving westward at 15 knots. Scattered showers and tstms are from 04N- 12N between 35W-45W. A tropical wave extends from 05N-17N with axis near 53W, moving westward at 15 knots. No convection is associated with this wave. A tropical wave is moving across the SW Caribbean S of 20N, with axis near 80W, moving westward at 15 knots. Numerous moderate to strong convection is S of 16N W of 77.5W. ...MONSOON TROUGH/ITCZ... The monsoon trough extends from 11N16W to 08N36W. The ITCZ begins near 08N55W and continues to 08N59W. Aside from the convection associated with the tropical waves, scattered moderate convection is from 05N-12N between 20W and 30W. GULF OF MEXICO... Stable conditions prevail across the Gulf supported by surface and middle level ridging. A weak pressure gradient across the region sustain moderate return flow in the western half of the basin and lighter winds elsewhere. Isolated showers are observed over the northern Gulf offshore waters. This shower activity is being supported by an upper level trough over the north-central basin and moisture inflow from both the Caribbean and a broad area of low pressure over the open waters SW of Manzanillo, Mexico in the E Pacific. Surface ridging will prevail over the Gulf waters through the middle of next week. Moderate to fresh E to SE winds are expected across most of the basin through Wed, except over the northeast Gulf, where light winds will prevail. CARIBBEAN SEA... High pressure N of the area continue to support fresh winds in the eastern and central Caribbean, except for fresh to strong in the south central basin. Otherwise, a vigorous tropical wave is producing heavy showers and tstms in the SW basin. See tropical waves section above. Fresh to strong trades will prevail across the south central Caribbean through the middle of next week. Winds may pulse to near gale force along the coast of Colombia tonight. A tropical wave is likely to approach the Lesser Antilles by the middle of next week. ATLANTIC OCEAN... High pressure continue to dominate the central, eastern and SW N Atlc waters, supporting fair weather. In the forecast, light to gentle winds will prevail across most of the SW N Atlc waters through early next week as high pressure extends across the area from the Central Atlantic. A trough passing through the area may bring some moderate to fresh westerly winds north of 28N for the start of next week. $$ Ramos
