.UPDATE...
Tropical Storm Emily continues to spin just off the Florida west
coast, with its center inside of 20 nm west of the mouth of Tampa
Bay. Most of the shower and thunderstorm activity is confined to
Pinellas and Hillsborough Counties southward and this should continue
to be the case for the next couple of hours, with the majority of the
activity shifting eastward through the day. Observations so far this
morning have shown wind gusts generally in the 30-40 mph range with
highest rainfall totals so far in the 3-5 inch range. The Flood Watch
remains in effect through today with several more inches of rain
possible. The ongoing forecast will continue to be updated through
the day.

.AVIATION...
Mainly prevailing MVFR/IFR conditions will continue for the next
several hours with brief periods of VFR possible. Waves of showers
and thunderstorms will continue to move across the region as Tropical
Storm Emily continues to move eastward. Wind gusts to 30 knots or
higher will be possible at times. Longer periods of VFR will become
more likely later today.

.MARINE...
Tropical Storm Emily over the eastern Gulf of Mexico will continue to
move eastward through today and tonight, with wind gusts to tropical
storm force possible through the day along with periods of heavy
rainfall and thunderstorms. Conditions will begin to improve later

thunderstorms will continue for the next several days.
