A sharp turn to the north is expected tonight or early Tuesday, and a generally northward motion is expected later on Tuesday. On the forecast track, the center of Franklin is forecast to reach the southern coast of Hispaniola by Tuesday night.

The estimated minimum central pressure is 999 mb (29.50 inches).

WIND: Tropical storm conditions are expected to begin within the warning area on Tuesday and are possible within the watch area beginning late Tuesday into Wednesday.
