Current Location: 17.5N/64.0W

Geographic Reference: 135 miles east-southeast of San Juan, Puerto Rico

Movement: West-northwest at 18 mph

Max Winds: 60 mph gusting to 70 mph


 Forecast: Irene is
moving to the west-northwest and this will take the center very near St.
Croix this afternoon and evening. This motion is expected to continue over
the next couple of days. On Tuesday and Wednesday, forecasters think Irene will
slow near the eastern tip of Cuba and turn more to the northwest. This
heading should last through Friday, which will take Irene into South Florida
Thursday evening. It is looking less likely that Irene will cross into the
Gulf of Mexico. There is a bit of uncertainty in the timing of the northwest
turn and for this advisory the forecast confidence remains below average
after Wednesday.

Environmental conditions remain very favorable for further
development. Forecasters have indicated that Irene will exhibit steady
intensification into a hurricane until it interacts with Hispaniola, which
will cause weakening to a tropical storm. Once Irene moves off of Cuba,
conditions are expected to be favorable for re-intensification. Irene could
regain hurricane intensity by the time it makes landfall in South Florida on
Thursday evening. Confidence in the intensity forecast remains low mainly due
to the uncertainties in how much weakening Irene will undergo over
