Special Marine Warning 21, NWS Tampa Bay, FL

Area Forecast Discussion
National Weather Service Tampa Bay Ruskin FL
1041 AM EDT Sun Apr 15 2018

.MORNING UPDATE...
An active weather day is anticipated with rounds of showers
and thunderstorms, a few of which may be severe. The
primary threat today will be damaging wind gusts. A band of
strong southerly winds exists from one to two thousand feet
off the ground. As storms move through this layer,
precipitation can mix these winds down to the surface,
resulting in gusts of 50 to 60 mph, and sporadic wind
damage. A low tornado threat also exists, mainly along the
Nature Coast where more directional wind shear is present.
Storms look to begin affecting the Nature Coast in the next
hour, shifting eastward and impacting the Tampa/St Pete
region through the mid to late afternoon, and eventually
into south Florida this evening. Strong gusty winds will
exist well ahead of the line of storms, with gusts of 30 to
40 mph possible in some areas. These winds will also impact
marine weather, with boating conditions expected to
deteriorate today, remaining unfavorable through tonight and
into Monday. Increasing surf will result in a high rip
current risk at area beaches as well.

The forecast is largely on track through tonight. Slight
modifications were made to PoP/weather grids to reflect the
evolution of storms across the region. Winds and wind gusts
were also nudged up over land just slightly.

&&

.AVIATION (12z TAFs)...
A powerful cold front will move through the area during the
period, bringing strong gusty winds up to 30 to 40 knots,
and a period of showers and thunderstorms. Low ceilings and
reduced visibilities will develop ahead of the line of
storms, and persist as they move through. Storms should
eventually clear all terminals after 00z with gusty winds
persisting.

&&

.MARINE...
Dangerous marine conditions will continue into tomorrow as
a powerful late season front moves across the waters. The
front will bring showers and thunderstorms with winds
gusting in excess of 30 to 40 mph at times. Sustained winds
of 20 to 25 knots will occur both ahead of and behind the
front, allowing seas to build to 9 top 10 feet offshore.
Despite improving winds Monday, seas will remain elevated
with small craft conditions persisting. By mid week, high
pressure will settle in over the waters with improving winds
and seas.
