360 AXNT20 KNHC 010405 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0605 UTC Fri Jul 1 2022 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 31N. The following information is based on satellite imagery, weather observations, radar and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0400 UTC. ...SPECIAL FEATURES... Potential Tropical Cyclone Two is centered along a tropical wave near 11.8N 77.7W at 01/0300 UTC or 360 nm E of Bluefields Nicaragua moving W at 18 kt. Estimated minimum central pressure is 1005 mb. Maximum sustained wind speed is 35 kt with gusts to 45 kt. Seas 12 ft or greater are within 180 nm from the center in the northeastern quadrant, with peak seas of 15 ft. Scattered moderate convection is noted from 10N to 15N between 73W and 82W. A westward motion will bring the system across the southwestern Caribbean Sea through Friday, crossing Central America Friday night, and emerging over the eastern Pacific Ocean on Saturday. The system is forecast to intensify through Friday with weakening expected as the system crosses Central America.

The axis of a tropical wave is in the E Atlantic near 29W, from 18N southward, moving west at 20 kt. Scattered moderate convection is observed from 04N to 08N between 23W and 31W. The axis of a strong tropical wave is near 56W, from 17N southward, moving west at 20 kt. A recent scatterometer pass found a distinct wind shift across the wave with fresh to strong winds on either side north of 12N. Scattered weak convection is observed from 10N to 16N between 49W and 59W. The axis of a tropical wave associated with Potential Tropical Cyclone Two is in the Caribbean near 77W, from 18N southward, moving west at 18 kt. Scattered moderate convection is noted from 10N to 15N between 73W and 82W. ...MONSOON TROUGH/ITCZ... The monsoon trough extends from the coast of Senegal near 14N17W to 08N26W. The ITCZ extends from 06N32W to 04N52W. Scattered moderate convection is observed within 180 nm of the ITCZ, east of 50W. GULF OF MEXICO... The gradient between high pressure ridging over the eastern Gulf and lower pressure over Mexico is generating moderate to fresh S-SE winds in the western Gulf with 3-5 ft seas. Moderate easterlies are impacting the SE basin, including the Florida Straits, with 2-4 ft seas. Winds are gentle in the NE basin with 1-2 ft seas. For the forecast, An area of low pressure located along the southern coast of Texas is forecast to move slowly northward and inland over southeastern Texas overnight. Active weather is expected to linger across the Texas coastal waters through Fri night. Otherwise, a ridge will dominate the Gulf waters through the upcoming weekend producing mainly gentle to moderate winds and slight to moderate seas. Fresh NE to E winds will pulse at night near the NW Yucatan peninsula through Mon night. CARIBBEAN SEA... Please see the SPECIAL FEATURES section for information on Potential Tropical Cyclone Two. Outside of the conditions associated with Potential Tropical Cyclone Two, strong easterly winds prevail over the central Caribbean with 8-12 ft seas. Moderate to fresh winds dominate the eastern Caribbean with 6-8 ft seas. Gentle to moderate winds prevail over the NW Caribbean with 3-5 ft seas. For the forecast, Potential Tropical Cyclone Two will begin to move W-SW overnight and reach near 11.5N 80.2W Fri morning as a Tropical Storm, near 11.3N 82.8W Fri evening, and then inland across southeastern Nicaragua Fri night, before continuing westward and emerging across the Pacific waters Sat evening. A strong tropical wave located along 57W is forecast to move over the Lesser Antilles on Friday and then over the eastern Caribbean Sea Fri evening through Sat night. Any development of this system should be slow to occur. Expect a broad surge of winds and seas across the Atlantic and Caribbean waters with this wave as it moves across the region. ATLANTIC OCEAN... The Azores high dominates the pattern in the Atlantic. In the western basin, mainly gentle winds and 3-5 ft seas prevail north of 27N and east of 77W while moderate SSE winds are observed off the Florida coast. Moderate to locally fresh easterly winds are noted south of 27N, including the Windward Passage, where seas are 5-8 ft. Fresh to strong winds are associated with the tropical wave approaching the Lesser Antilles with 8-10 ft seas. In the eastern Atlantic, NE winds are moderate to fresh with 7-9 ft seas north of 17N with gentle winds and moderate seas south of 17N. For the forecast W of 65W, the Atlantic ridge will continue to dominate the forecast waters through the upcoming weekend. The pressure gradient between the ridge and Potential Tropical Cyclone Two will support fresh to strong NE to E winds N of Hispaniola and in the Windward Passage through Fri night. Then, a strong tropical wave forecast to move over the eastern Caribbean Sea by the weekend will bring a surge of winds and seas across the waters S of 22N Fri night through Sun. $$ Flynn
