...SPECIAL FEATURES...

Post-Tropical Cyclone Teddy is centered near 46.0N 61.3W at
23/01500 UTC or 130 nm NE of Halifax Nova Scotia moving NNE at
23 kt. Estimated minimum central pressure is 967 mb. Maximum
sustained wind speed is 50 kt with gusts to 60 kt. Scattered
moderate convection is within 480 nm of the center in the NE
quadrant and 240 nm in the NW quadrant. Please, read the latest
NHC Public Advisory at:
https://www.nhc.noaa.gov/text/MIATCPAT5.shtml, and the Forecast/
Advisory at https://www.nhc.noaa.gov/text/MIATCMAT5.shtml, for

...TROPICAL WAVES...

An Atlantic Ocean tropical wave is along 27W, from 16N
southward, moving W 10 to 15 knots. No significant convection is
associated with this wave.

A weak Atlantic Ocean tropical wave is along 39W, from 20N
southward, moving W 10 to 15 knots. No significant convection is
associated with this wave.


...MONSOON TROUGH/ITCZ...

The monsoon trough passes through the coastal sections of Guinea
near 10N14W, to 07N26W. No significant convection is occurring
along this trough.

GULF OF MEXICO...

The remnants of Beta are located in southeast Texas. Winds and
seas have diminished on Gulf waters, and all convection is now
inland.

The tail end of a stationary front extends from Cuba near 22N80W
to 24N86W to the SE coast of Louisiana near 29N91W. Scattered
moderate convection is within 60 nm of the front.

The stationary front from the Central to SE Gulf will remain
over the southeast Gulf and gradually weaken through the week.
Fresh E winds to the east of this front will gradually diminish
Thu.

CARIBBEAN SEA...

A stationary front N of Hispaniola and Puerto Rico is inducing
scattered moderate convection from 19N-21N between 62W-66W.

Scattered moderate convection associated with the Pacific
monsoon trough is occurring off the Panama and Colombia coasts,
S of 14N.

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 has arrived in
Atlantic passages and will continue into Thu 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...

The remnants of Paulette are located between the Azores and
Canary Islands and should diminish in a day or two as a cold
front absorbs Paulette.

A stationary front extends from the W Atlantic near 31N56W to
21N70W to Cuba near 21N80W. Scattered moderate convection is
within 60 nm of the front.

A surface trough is noted from 21N48W to 14N55W. Scattered
showers are within 60 nm of the trough.

Over the W Atlantic, swell previously generated by Hurricane
Teddy and a cold front that moved through at the start of the
week will only gradually subside by Thu night. Generally gentle
to moderate easterly winds can be expected for the remainder of
the week.
