156 PM EDT Mon Apr 10 2017

overnight into Tuesday along the east coast.

.PREV DISCUSSION... /issued 939 AM EDT Mon Apr 10 2017/

..Fire Weather Watch now in effect for inland Southwest Florida
on Tuesday...

UPDATE...
Easterly flow continues across the area this morning, with showers
pushing ashore from the Atlantic. Forecast handles the situation
well, so minimal changes were necessary at this time. The main
changes were refreshes to the hourly wind grids using the latest
high-resolution guidance which was a knot or two higher than
previous runs for today. Otherwise, things remain the same across
South Florida forecast-wise. A Fire Weather Watch was issued for
tomorrow for the same area as today's Red Flag Warning. The
concern for low relative humidity values exists from northern
Collier County into Glades County on Tuesday afternoon. Will allow
the next shift to assess the threat and possibly upgrade the watch
to a Red Flag Warning if the fire weather threat materializes.

PREV DISCUSSION... /issued 415 AM EDT Mon Apr 10 2017/

DISCUSSION...
Strong high pressure across the region will gradually migrate east
and into the western Atlantic through the week while keeping a
generally benign weather pattern over South Florida.

A few light showers are still possible, mainly around the
Atlantic coast, but any shoer that develops should be brief.
Meanwhile,models depict a localized trough developing east of the
Bahamas during the next couple of days, which gradually moves to
the northeast and away form the area. Pressure gradients will
become tighter between the aforementioned high and the developing,
resulting in periods of breezy easterly winds over South Florida
along with a high risk of rip currents along the Atlantic beaches
today and possibly through mid week.

A warming trend continues today with highs climbing into the mid
80s each day this week, and lows hovering the low to mid 60s
interior/west coast areas, and around 70 over most locations of
the Atlantic coast each night. Some patchy smoke from the NE
Collier county is possible today.

EXTENDED FORECAST... mostly dry weather continues through next
weekend with prevailing easterly flow, except for a few brief
showers possible over the Atlantic coast.

MARINE...
Easterly winds prevail through mid week, increasing 15 to 20 knots
today. The Atlantic seas will be increasing to 5 to 7 feet later
today and into Tuesday, while the Gulf seas will remain below 6
feet through mid week. Small craft should exercise caution over
the Atlantic waters starting today.

BEACH FORECAST...
The stronger winds will keep a high risk of rip currents,
today at all coastal areas of the Atlantic coast. The risk of rip
currents over the Atlantic coast will likely last through much of
the work week.

FIRE WEATHER...
Relative humidity values will again fall down below 40 percent for
4 hours or more over the western interior areas today, and down into
the 40s over rest of South Florida. Therefore, the Red Flag Warning
for the western interior areas remains in effect through tonight.
Another day of critical humidities is possible on Tuesday.
