Previous Forecast

Due to Chantal’s current motion, forecasters
are expect the system to move through the Leeward and Windward Islands in about
24 to 30 hours. This is about 6 hours sooner than was indicated in the previous
advisory. The impacts will likely begin late this evening and last through
tomorrow afternoon. The intensity forecast has also been modified. Forecasters
are now forecasting Chantal to remain a tropical storm through the next 5 days.
This is based upon the latest model guidance. The 25 mph wind radii were also
reduced, especially to the west of the center. This was based upon the latest
satellite data.


Tropical Storm Chantal continues
rapidly to the west. With the exception of the faster forward speed, there are
few changes to the track forecast through the next 5 days. However, beyond 5
days, the latest models are indicating an increasing threat to the southeast
United States. It appears as if the greatest threat lies from north Florida
through South Carolina. Any impact in this area likely will not occur until

The latest satellite data indicate that winds remain at 40 mph.
With the exception of keeping Chantal as a tropical storm through the next 5
days, there has been no change to the intensity forecast. Environmental
conditions still appear as if they will become more hostile once Chantal enters
the eastern Caribbean. 50 mph remains the peak intensity. It should be stated
that this is somewhat below the intensity forecast guidance. If the environment
does not become as hostile as forecast, Chantal will likely become a strong
tropical storm in the eastern Caribbean.
