.DISCUSSION...
Issued at 246 PM EDT Sat Oct 5 2024
A very serious situation is beginning to develop for West Central
and Southwest Florida. A deep moisture axis is overspreading the
region ahead of a sinking frontal boundary. When combined with
moisture and instability, this means scattered to numerous showers
and thunderstorms across the region over the next few days, with a
high potential for flooding to occur, necessitating a flood watch.
This is ahead of the main event for the week: Tropical Storm Milton.
Key Points:
* Milton is expected to quickly intensify while it moves E to NE
across the Gulf and will be at or near major hurricane strength as
it reaches the west of Coast of Florida beginning late Tuesday or
Wednesday.
* There is an increasing risk for life-threatening storm surge and
wind impacts beginning late Tuesday into Wednesday
* Areas of heavy rainfall will impact the area starting tomorrow and
will continue through mid-week
After Milton passes, weather conditions will gradually improve. High
pressure settles in, with a slightly cooler and drier airmass
settling in.

.AVIATION...
(18Z TAFS)
Issued at 246 PM EDT Sat Oct 5 2024
We are in for a wet period starting this afternoon and continuing
through at least mid-week. We`re already seeing SCT/BKN clouds
around 4kft this afternoon and isolated SHRA over SW FL and will
continue through the period. Scattered SHRA and isolated TSRA will
be possible this afternoon/evening with highest chances over SW FL.
Will cover this with VCTS for now and tweak as needed based on radar
trends. Moderate rain chances persist through much of tomorrow, so
will hold SHRA starting at 08Z and continuing through the day on
Sunday. Easterly winds around 5-10 knots expected through Sunday
morning, then increasing to around 8-12 knots with gusts near 18
knots possible late morning and into the afternoon.&&
.MARINE...
Issued at 246 PM EDT Sat Oct 5 2024
Easterly winds continue through the weekend, with typical evening
showers and thunderstorms this afternoon. Rain chances increase
tomorrow and into early next week as an axis of moisture spreads
across the region. Marine conditions will deteriorate through the
week as Tropical Storm Milton strengthens into a hurricane. Life-
threatening marine conditions are possible by the middle of the
week.

.FIRE WEATHER...
Issued at 246 PM EDT Sat Oct 5 2024
Ample moisture will preclude any fire weather concerns.

.HYDROLOGY...
Issued at 246 PM EDT Sat Oct 5 2024
A very wet pattern is settling across the region through mid-week as
first a deep moisture axis overspreads the region, and then
eventually Milton makes its way across the Gulf to the West Coast of
Florida, intensifying into a hurricane. Heavy rainfall is a
significant concern, with the potential for extensive, widespread
flooding that will be compounded by ongoing cleanup efforts from
Helene. A Flood Watch is now in effect from tomorrow (Sunday)
morning until Thursday morning.
