.SHORT TERM...
(Rest of today through Tuesday)
Issued at 136 PM EDT Mon Sep 16 2024

Potential Tropical Cyclone Eight moves into the Carolinas as a mid-
level trough sits over the southeastern United States. High pressure
over the northeastern United States will block a path north for the
remnants of Eight as it becomes absorbed into a developing mid-level
low and an associated frontal boundary currently north of our area
advances across the peninsula of Florida tonight into Tuesday. The
warm, wet, and unsettled pattern will continue through the short
term period thanks to the aforementioned synoptic scale features,
diurnally-driven sea breezes, and continued rich low-level moisture.

Some vigorous thunderstorms are possible this afternoon with the
primary concerns being strong to locally damaging wind gusts and
localized flooding due to excessive rainfall. Boundary interactions
today and again on Tuesday could provide a focus for more vigorous
convection. More cloud cover earlier on Tuesday compared to previous
days could help keep heat index values in check and potentially end
the string of Heat Advisories.

.LONG TERM...
(Tuesday night through next Sunday)
Issued at 254 PM EDT Mon Sep 16 2024

Models remain in fair agreement by keeping a trough/low complex
dominating most of the SE CONUS through the end of the work week,
then the low quickly migrates further NE and away from the region
for the weekend. Regardless of the low developing into a tropical
system, it will continue to keep pressure gradients against the
Atlantic high fairly weak, resulting in weak prevailing weak to calm
sfc winds over SoFlo through much of the long term period.

At the mid/upper levels, flow should remain generally from the SW or
W, with modest moisture advection in place. Global solutions depict
some mid level drier air intrusion into the mid levels from the
GOMEX, which is expected to help in lowering PWATs to near normal
values. However, enough low level moisture should linger over the
area for POPs to remain at or above 50 percent each afternoon.

Latest model PWATs remain around the 1.8 to 2.2 inch range, so
expect scattered to numerous showers and thunderstorms daily. The
prevailing weak sfc winds will keep storm motion rather erratic,
with sea breezes and outflow boundaries becoming the main lifting
mechanism and source for instability, thus acting as foci for deep
convection. Also, the SW flow aloft will keep a rain pattern that
favors SoFlo`s interior and eastern metro areas. Max POPs remain in
the 50-60% range each day.

In terms of temps, afternoon highs are expected to moderate a little
and fall back to seasonal normals (upper 80s-low 90s). However, peak
heat indices will likely remain in the low triple digits, but should
remain just below heat advisory criteria.

.AVIATION...
(06Z TAFS)
Issued at 135 AM EDT Tue Sep 17 2024

Mainly VFR conditions will prevail through the overnight hours.
Light and variable winds will increase out of the SSE early
Tuesday afternoon as the east coast sea breeze pushes inland.
Scattered to numerous showers and storms will develop Tuesday
afternoon as the sea breeze moves inland. These storms could bring
periods of sub-VFR conditions to the east coast terminals during
the late afternoon and early evening hours. At KAPF, winds will
increase out of the SW this afternoon as a Gulf breeze develops.

.MARINE...
Issued at 136 PM EDT Mon Sep 16 2024

Generally light south to westerly winds will prevail through most of
this week as a weak surface boundary and Potential Tropical Cyclone
Eight remain north of the area. Seas across the northern Atlantic
waters will remain elevated through this afternoon as northerly
swell generated by Potential Tropical Cyclone Eight offshore of the
southeastern United States moves in. Scattered showers and
thunderstorms will be possible each day through the period and could
lead to locally higher winds and seas.

.BEACHES...
Issued at 136 PM EDT Mon Sep 16 2024

Ongoing northerly swell associated with Potential Tropical Cyclone
Eight and its remnants will result in a continued elevated rip
current risk through the middle part of the work week along the
Atlantic beaches of South Florida as the swell gradually subsides.

There will also be the continued potential for minor coastal
flooding around periods of high tide due to astronomically higher
tides associated with this full moon through mid-week. A Coastal
Flood Statement is in effect through at least Wednesday.

High Tide Times:

* Naples: 12:05 pm Monday, 1:01 am Tuesday, 12:56 pm Tuesday
* Lake Worth: 7:27 pm Monday, 7:46 am Tuesday, 8:14 pm Tuesday
* Port Everglades: 7:44 pm Monday, 8:06 am Tuesday, 8:31 pm Tuesday
* Virginia Key: 8:30 pm Monday, 8:53 am Tuesday, 9:18 pm Tuesday
