Precipitation: isolated moderate to locally strong is from 27N southward from 91W eastward. Isolated to widely scattered moderate and isolated to locally strong is in the interior and coastal waters areas of Cuba. Broad low pressure, from the surface upward into the atmosphere, extends from the upper Texas coast of the Gulf coast, southward to Mexico, near 20N. Tropical Depression Beta is weakening in southeastern Texas, and it will have no more impacts on the area waters. A stationary front, from the central Gulf of Mexico into the SE Gulf, will remain in the southeast Gulf of Mexico, and gradually weaken through the week. Fresh E winds, to the east of this front, will diminish gradually on Thursday. CARIBBEAN SEA... A stationary front passes through 22N70W in the Atlantic Ocean, cutting across Cuba, to 25N86W in the SE Gulf of Mexico.

Isolated to widely scattered moderate and isolated to locally strong is in the interior and coastal waters areas of Cuba. The monsoon trough is along 09N/11N, from 73W in northern Colombia beyond Costa Rica, into the eastern Pacific Ocean. Precipitation: isolated moderate to locally strong is from 17N southward from 70W westward. The upper level wind flow that is in the Caribbean Sea from 70W westward is moving away from an upper level ridge, and toward an inverted trough. The trough is in the western sections of the Caribbean Sea, from the Yucatan Peninsula toward northern sections of Colombia. Northerly swell, previously generated by Hurricane Teddy and an early season cold front in the western Atlantic Ocean, will arrive overnight to the Atlantic Ocean passages and continue through Thursday 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 stationary front is along 32N57W to 27N60W and 22N70W, cutting across Cuba, to 25N86W in the SE Gulf of Mexico. Precipitation: widely scattered moderate to isolated strong is from 20N northward between 47W and 60W. Isolated moderate to locally strong is elsewhere from 18N to the stationary front between 60W and Hispaniola. isolated to widely scattered moderate and isolated to locally strong is in the interior and coastal waters areas of Cuba. A surface trough curves from 23N45W to 16N50W to 12N60W. Precipitation: isolated to widely scattered moderate and isolated strong is within 200 nm to the east of the trough, and within 120 nm to the west of the trough. A surface trough is along 24N27W, to a 1013 mb low pressure center that is near 10N28W, to 18N27W. Precipitation: isolated moderate is within 120 nm on either side of the trough. Swell previously, generated by Hurricane Teddy and a cold front that moved through the area at the start of the week, only will subside over the area gradually. Comparatively higher seas will persist through Thursday night. High pressure, building down the east coast of the U.S.A., will lead to fresh NE winds, to the N of the Bahamas through Wednesday. Gentle to moderate easterly winds take hold, after that time, for the remainder of the week. $$ mt
