.SHORT TERM...
(Tonight through Saturday night)
Issued at 156 AM CDT Fri Oct 18 2024

Key Messages:

- High risk of rip currents through Saturday night

- Minor coastal flooding expected through Saturday night

Temperatures today and Saturday will be much like yesterday with
afternoon temperatures in the low to mid 80s and overnight lows in
the 60s. Moderate to strong, generally easterly flow will
continues allowing low- level moisture to return slowly to the
area. A very low (<20%) chance of showers will be possible late
today and tonight as a shortwave tracks along the northern
portions of the area. Another weak shortwave will move across the
area Saturday afternoon, which will lead to a low (10-20%) chance
of showers.

Minor coastal flooding and high risk of rip currents will continue
through Saturday night. Water levels are expected to reach the
dunes during periods of high tide. Notably, the levels have been
slow to recede. P-ETSS continues to indicate levels reaching a bit
above 2.5 ft MSL.

.LONG TERM...
(Sunday through next Thursday)
Issued at 156 AM CDT Fri Oct 18 2024

Key Messages:

- Minor coastal Flooding and moderate to high rip current risk
expected to continue into early next week.

Main hazards expected for the upcoming week continues to be minor
coastal flooding and moderate to high risk of dangerous rip
currents. Confidence is moderate (40-60%) that these conditions will
occur due to projected swells around 8 to 9 seconds combined with a
moderate to strong easterly wind across the gulf and astronomically
high tides through Monday. The P-ETSS is indicating tide levels
reaching 2.5ft above MSL Sunday and Monday. Conditions are expected
to improve beginning Tuesday when winds and swells are progged to
subside.

Otherwise, S TX will see a slight chance of showers and
thunderstorms Sunday, then drier with a gradual warming trend
through the middle of next week. Models prog mid level low pressure
to be northwest of TX with high pressure over the NW Gulf of Mexico,
placing S TX under a southwest flow aloft by Sunday. The low
pressure to the northwest will lead to deepening surface low along
the rockies, which will result in a tight gradient along the TX
coast. This will lead to moderate to strong generally east winds
which will usher deeper moisture into S TX. PWATs are progged to
increase to around 1.5 inches which is slightly above normal for
this time of year. The increased moisture combined with an embedded
short wave aloft will bring a low (10-20%) chance of showers and
thunderstorms on Sunday, mainly across the southern portions of the
CWA where the moisture is deepest. High pressure then builds back
across S TX, bringing drier mid levels across the region by early
next week. As a result, temperatures will be on the increase and
rain chances will drop below 10% through Thursday of next week.
