Previous Forecast

5:00AM – Forecasters shifted the track slightly more to the west for the
segment in the eastern Gulf of Mexico. This reflects their thinking of a
landfall late Tuesday or early Wednesday near the Florida/Alabama border.

Forecast

Isaac is moving to the West. On
this track, it will pass near the southwestern coast of Haiti this afternoon
and evening. Saturday through early Sunday Isaac will track across eastern and
central Cuba. Forecasters expect Isaac to gradually turn to the northwest,
bringing it near the Florida Keys and into the southeastern Gulf of Mexico
Sunday night. It is possible it could be a hurricane before reaching the
Florida Keys. Forecasts think that the most likely landfall point would be near
the Florida/Alabama border. The most recent model runs suggest that the
westward shift in the tracks may have ended. However, there is still a chance
that additional westward adjustments may be needed in subsequent forecasts.

Isaac remains disorganized this morning. The center is on the
north edge of the deep thunderstorms. Isaac is unlikely to become a hurricane
in the Caribbean. Satellite data and surface observations indicate that the 25
mph wind field extends out from the center 300 to 400 miles on the north side.
This indicates a large circulation, but not an intense one at this time. Some
consolidation and strengthening is forecast before the center reaches the coast
of southwestern Haiti and Cuba. Interaction with Cuba will hamper
strengthening. However, conditions are expected to be more favorable in the
Florida Straits and Gulf of Mexico. Forecasters think Isaac could be a Category
1 hurricane in the southeastern Gulf of Mexico on Monday, and a Category 2
hurricane in the northeastern to north-central Gulf of Mexico on Tuesday. Warm
water in the Gulf and low to moderate wind shear will allow for strengthening
to occur. Therefore, forecasters cannot rule out the chance that Isaac could
become a Category 3.

Expected Impacts on Land

Virgin Islands and Puerto Rico: Some
additional rain bands could move through over the next 12 hours with wind gusts
up to 50 mph.

Dominican Republic: Squalls
will continue through today. Heavy rainfall, flooding, and mudslides are likely
throughout the island of Hispaniola. Tropical storm force winds are possible
through today.

Jamaica: Squalls
could reach the island by late this morning. The worst conditions would be
tonight through midday Saturday.

Florida: Squalls
are forecast to begin spreading over the state early Sunday morning and spread
northward in tandem with Isaac.

Expected Impacts Offshore

Central Caribbean: Over the
next 24 hours, tropical storm conditions are likely.

Eastern Gulf of Mexico: Sunday
night, the first squalls will move into the southeastern Gulf and spread
northward.

North-Central Gulf of Mexico
Lease Areas: 
Squalls could be reaching the deepwater areas off southeast
Louisiana as early as Monday morning. Our forecast has the center of Isaac
passing about 90 miles east of Mississippi Canyon midday Tuesday.

 

TROPICAL STORM JOYCE

 

Current Location: 16.8N/44.1W

Geographical Reference: 1495 miles
SE of Bermuda

Maximum Sustained Wind: 35 mph
gusting to 45 mph

Movement: WNW at 18
mph

Organizational Trend: Weakening

Forecast Confidence: Average

Previous Forecast

Joyce has weakened to a tropical
depression but may regain tropical storm strength in 24-48 hrs.

Forecast

Satellite imagery indicates that
Joyce has weakened to a tropical depression, and the cyclone has been
downgraded to a depression by the National Hurricane Center. However,
conditions aloft may become favorable for some strengthening should Joyce’s
circulation remain intact over the next 24 to 48 hours. Our forecast takes
Joyce generally toward Bermuda, and then it accelerates out to sea to the
northeast.

Joyce will not be threatening the Caribbean however the system
will be monitored until it  has dissipated.
