1. Northern Leeward Islands (AL94):
Surface observations indicate a small area of low pressure is
located over the northern Leeward Islands. The system continues to
produce showers and thunderstorms this morning, but they have not
become any better organized. Environmental conditions, including the
proximity of dry air, do not favor development of this system while
it moves west-northwestward at about 15 mph. Regardless of
development, locally heavy rainfall and gusty winds are possible
across the northern Leeward Islands today.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...low...20 percent.
