between 16W-23W.

An Atlantic Ocean tropical wave is along 38W from 03N-17N, moving
W at 15-20 kt. A 1010 mb low pressure along the wave axis near
08N38W. Scattered showers are within 180 nm of the wave axis.

A eastern Caribbean Sea tropical wave is along 60W from 04N-16N,
moving W at 15-20 kt. Widely scattered moderate convection is
within 180 nm of the wave axis.

A central Caribbean Sea tropical wave is along 72W from 06N-17N,

Bissau near 13N16W to 10N30W. The ITCZ continues from 10N30W to
08N36W. The ITCZ resumes W of a tropical wave near 07N42W and
continues to the coast of N Brazil near 04N51W. Besides the
convection mentioned in the tropical wave section, a large area of
scattered moderate to strong convection is inland over W Africa
from 06N-15N between 09W-15W.

GULF OF MEXICO...

T.S. Barry is over the north central Gulf of Mexico. See the
SPECIAL FEATURES section above.

Scattered moderate convection is also over the NE Gulf and over
north and central Florida. More scattered moderate convection is
over W Cuba. Elsewhere, patches of scattered moderate to isolated
strong convection is inland over S Mexico between 90W-99W. In the
upper levels, a small upper level high is centered over E Texas
near 30N94W producing some shear over T.S. Barry.

Tropical Storm Barry will move to 29.2N 91.3W tonight, strengthen
to a hurricane, then move inland over Louisiana near 30.1N 91.9W
Saturday afternoon. Barry will weaken and move farther inland near

CARIBBEAN SEA...

A tropical wave is entering the E Caribbean Sea. Two other
tropical waves are also over the Caribbean. See above. In
addition, widely scattered moderate convection is over E Cuba and
Jamaica. In the upper levels, strong subsidence is over the
central and eastern Caribbean.

High pressure N of the area will support fresh to strong trade
winds over the S central Caribbean for the entire period. Winds
will be fresh to occasionally strong over the Gulf of Honduras.

ATLANTIC OCEAN...

Scattered moderate convection is seen along the NE Florida coast N
of Daytona Beach. Scattered showers and isolated thunderstorms are
also over the N Bahamas. A surface trough is over the N Bahamas
from 28N79W to 23N79W. A 1019 mb high is centered over the W
Atlantic near 27N70W. A 1016 mb low is centered further E near
30N55W. Scattered showers are within 120 nm of the low. A 1025 mb
high is centered over the Azores near 38N26W.

Over the W Atlantic, a trough will move westward across the
waters S of 27N Saturday through early Tuesday when it will reach
the Florida Peninsula. Otherwise, high pressure will dominate the
region through early next week, generally bringing gentle to
