Changes From Our Previous
While forecasters think wind
shear will be an inhibiting factor in the Caribbean Sea, it may not be enough
to prevent Chantal from strengthening modestly. Forecasters think it could
reach peak intensity near 65 mph before reaching Hispaniola, which is about 15
mph stronger than the previous update. The only other major change that
revolves around their thinking is Chantal’s track beyond the next five days.
Since this morning, the model guidance has trended westward in the 5-7 day time
period. Thus, forecasters think Chantal could reach Florida in about 6 days.
Chantal is now moving to the
west-northwest at a brisk pace. On this path, the center should reach the
Lesser Antilles around midday Tuesday. Chantal should gradually decelerate in
the Caribbean Sea on its way to Hispaniola. On a west-northwest path, Chantal
should reach the Dominican Republic on Wednesday. Further deceleration is
expected as Chantal exits Haiti and enters Bahamian territory early Friday. A
weakness in the subtropical ridge should allow the storm to move northward
through the Bahamas Friday and Saturday. Per the last few model runs, forecasters
think that Chantal could turn toward Florida as the subtropical ridge rebuilds
westward. Forecasters do want to rule out the possibility that Chantal is
driven across Florida and finds itself in the eastern Gulf of Mexico about a
week from now. Forecasters confidence in the first 5 days of the forecast track
is about average.
Environmental conditions are good enough to allow Chantal to gain
strength, becoming a 65 mph tropical storm by the time it reaches Hispaniola.
The attainment of hurricane strength is not likely, nor forecasted, but the
possibility should not be discounted. Chantal will weaken across the rugged
terrain of Hispaniola and emerge in Bahamian waters by early Friday. Upper
level winds could hamper restrengthening while Chantal is over the Bahamas
Friday and Saturday. Forecasters confidence in the intensity forecast is good
through the first 48 hours, with less confidence in the following days of the
