Advisory NPW Special Advisory — Thu Jun 27, 2024 10:12 AM

NPWSJU) was issued for Puerto Rico and the U.S.
Virgin Islands once again. Maximum temperatures should reach the low
90s across most coastal municipalities with heat indices reaching or
exceeding 110F. Easterly winds around 15 mph with stronger gusts are
expected during the day.

.LONG TERM...Sunday through Thursday...

The long term forecast is based on the forecast trajectory of a
couple of tropical disturbance that area expected to move south
of the local area. We are currently monitoring two tropical weather
systems. The first system has a higher potential for development,
however, a high pressure area will keep it positioned well to the
south of our region. The second tropical wave is not forecasted
to develop as significantly,but models suggest it will be located
somewhat closer to the local region. While it might initially
appear that neither of these systems will have a direct impact on
our area, they will indeed indirectly affect us. Both systems
will lead to increased cloudiness and higher likelihood of rain.
Our primary concern, however, is the hazardous marine conditions
anticipated, particularly in the Caribbean Sea, due to the
forecasttrack of both systems. The first wave now Invest 95L is
forecast between late Monday and Tuesday and the second wave is
forecast to move south of the area between Wednesday and Thursday.

.AVIATION...

(06Z TAFS)

Mainly VFR conditions are expected to prevail across all terminals
during the next 24 hours. However, MVFR conds are possible across
the area terminals btw 27/15z-22z as a trough streams over the area
from the east. East winds expected at 12-16 kt with stronger gusts
and sea breeze variations aft 27/14z.

.MARINE...

A surface high pressure over the central Atlantic, extending all
the way to the Caribbean, will hold a moderate easterly wind
pattern across the region. Therefore, seas will remain between 3
and 4 feet, even less for the coastal waters. By the beginning of
the upcoming workweek, building seas are forecast as a vigorous
tropical wave, now monitored by the National Hurricane Center,
moving over the Caribbean Waters, increasing the seas to 8 feet.
Mariners should keep track of the tropical forecast for further
updates on the expected conditions. Also, regarding the moisture
field that accompanied the tropical wave, the forecast calls for
thunderstorm activity, which could lead to even more localized
hazardous conditions. For the coastal areas, the risk of rip
currents will continue to moderate for some areas and low for the
rest of the areas.
