Advisory NPW Special Advisory — Thu Sep 26, 2024 12:00 PM

NPWSJU) was issued for the coastal areas
of PR.

LONG TERM...Sunday through Wednesday...

After the passage of a weak tropical wave across the islands on
Saturday, a drier airmass is expected to quickly move into the area.
Therefore, mainly calm and stable weather conditions are anticipated
from Sunday onward. A migrating surface high pressure located over
the Bahamas and moving into the central Atlantic will promote
easterly winds until Tuesday. On Wednesday, this surface high is
expected to be located north or over the local islands promoting
winds from the northeast. Shower activity will be limited during
this period. However, passing showers dragged by the trade winds
cannot be ruled out across the eastern municipalities of Puerto Rico
and the USVI. In the afternoon hours, some localized showers are
possible due to the combination of moisture, warm temperatures and
local effects. Hot temperatures are very likely during most of the
long-term period with highs reaching the mid 90s along the coastal
and urban areas. Precipitable water will be mostly between 1.55 to
1.80 inches from Sunday through at least late Tuesday.

AVIATION...

(06Z TAFS)

SHRA and -TSRA en route from the Leeward Islands may cause brief
MVFR conds at times across TIST/TISX/TJSJ thru 26/15z. Thereafter,
SHRA/TSRA expected to spread across the interior and western
sections of PR, causing possible TEMPO MVFR conds at TJPS btw 26/18z-
22z. Elsewhere, VCTS expected. East winds expected at 10-15 kt with
locally higher gusts and sea breeze variations aft 26/14z.

MARINE...

A weak high pressure ridging over the region will maintain gentle to
moderate easterly winds over the next few days. A northerly swell
will maintain seas to around 4 to 5 feet through the weekend.
Shower and thunderstorm activity will increase from today into
Friday as a tropical wave approaches our region.

BEACH FORECAST...

There is a moderate risk of rip currents along the northern side
of most of the islands. The risk may become high for the north-
facing beaches of Puerto Rico and Culebra on Friday morning.
