Area Forecast Discussion
National Weather Service San Juan PR
241 PM AST Fri Aug 8 2025
.KEY MESSAGES...
* The US Virgin Islands will have daily showers and warm to hot
heat indices from mid-morning to afternoon each day.
* The interior and western PR can expect showers and
thunderstorms producing flooding rains today.
* The warm-to-hot spell trend will persist throughout most of the
forecast period, especially during the peak of daily heating.
* An induced surface trough will likely bring moderate to heavy
rain, starting in the northern US Virgin Islands late tonight
and continuing into early Saturday morning. The rain will then
spread to eastern Puerto Rico and move into the interior and
western regions by Saturday afternoon.

.SHORT TERM...Tonight through Sunday...
Both the US Virgin Islands and Puerto Rico experienced a
combination of sunshine and clouds, with hazy skies due to the
presence of low to moderate concentrations of suspended Saharan
Dust Particles. Occasional showers, advected by the prevailing
winds, moved inland over the islands. The heat indices rose above
100 degrees Fahrenheit, while maximum temperatures reached the
upper 80s and low 90s during the mid-morning to peak heating hours
in many urban and coastal areas. By early afternoon, Doppler
radar observed most weather activity downwind from the USVI over
water, with the ones from St Thomas affecting Culebra and eastern
Puerto Rico. We detected another round of convection over the
interior near Adjuntas and western PR, near Cabo Rojo. Winds
predominantly flowed from the east, with fluctuations due to the
sea breeze.
Today's afternoon convection will continue, especially across
western PR through this evening, where urban and small stream
flooding will remain possible with the most vigorous activity.
Additionally, the USVI can expect calm conditions with above-
normal temperatures overnight, with an increase in showers
associated with the proximity of an induced surface trough late
tonight into early Saturday morning, producing ponding of water in
roads and poorly drained areas. Elsewhere, Puerto Rico and St
Croix can expect tranquil weather conditions, with a few
occasional showers over the windward locations overnight.
Although the induced surface trough will increase the available
moisture as well as the potential to observe rain activity, we are
forecasting that some locations, especially near St Croix,
Vieques, the southeast, southern, and western PR, can expect calm
weather Saturday morning. However, occasional to frequent passing
showers could impact the windward locations along the northern US
Virgin Islands and east and north PR, followed by strong afternoon
convection, especially along and north/west of the Cordillera
Central. Some places across the interior and northwest PR can
expect an elevated chance to observe flooding rain and isolated to
scattered thunderstorms. The locations that do not observe rain
will experience above normal heat indices due to the moisture
increase.
Moisture erosion is forecast for Sunday, with a typical weather
pattern, consisting of passing showers across the windward
locations and a mixture of sunshine and clouds elsewhere, followed
by afternoon convection over the western sections in PR and
downwind from the USVI.
The warm-to-hot spell trend will persist throughout the short
term, extending into early next week, especially during the peak
of daily heating.
.LONG TERM...Monday through Friday...Previous Discussion...
The uncertainty for the long term forecast continues regards the
development of a tropical wave, Invest 96L, located over the central
tropical Atlantic with a formation chance of 40% in the next 7
days. The latest model guidances continues to suggest the passage
of the wave to the northeast of the region and away over the open
Atlantic waters on Monday. However, trailing moisture associated
with this system will reach the islands by early Tuesday.
Therefore, enhancing the potential to observe showers and isolated
thunderstorms across the U.S. Virgin Islands and Puerto Rico.
By Wednesday, a mid-to-upper level ridge will place over the
northeastern Caribbean promoting drier and stable conditions aloft.
A dense Saharan Air Layer (SAL) is expected to arrive into the
region from mid-week onwards, with moderate to high concentrations
of Saharan dust particles. Under the aforementioned conditions,
limited shower activity is anticipated during this period.
The 925 mb temperatures will remain at normal to above-normal
climatological values for next week. Highs will remain in the upper
80s to low 90s along the coastal and urban areas, and from the low
to mid 80s in the higher elevations. Heat indices will continue over
the 100 degrees Fahrenheit each day. Plan accordingly if planning to
do outdoor activities under sun exposure.
By the end of the workweek, model guidances are suggesting a
strong tropical wave to move into the central Atlantic. However,
there is a lot of uncertainty regarding the future of this system
as it is too early to specify possible impacts, if any, to our
region. Residents and visitors are strongly encouraged to stay
informed and monitor future forecasts as we move into next week.

.AVIATION...
(18z TAFs)
Mostly VFR conds across all TAF sites. TSRA/+SHRA will form along
and west of the Cordillera Central, impacting JBQ thru this
evening (08/23z), with VCTY near JPS or even JSJ. SHRA will form
downwind from the USVI, remaining in the VCTY of IST/ISX. SHRA
will increase in frequency btwn 09/02-10z near IST. +TSRA/+SHRA
could develop tomorrow (09/16-23z). Expect winds from the E-ESE at
10-15 with higher gusts thru 8/23z, and btwn 09/13-23z, but calm
to light and VRB btwn 08/23z-09/12z.
&&
.MARINE...
Mariners can expect a moderate to fresh easterly wind flow
generating moderate chops across the local waters. Afternoon
convection will develop across the Mona Passage daily. An induced
surface trough will increase rain activity and the potential for
thunderstorms from late tonight/early Saturday morning, into the
afternoon. Invest 96L will move far to the northeast from the
northern USVI around Monday or Tuesday.
&&
.BEACH FORECAST...
Thunderstorms could form each afternoon near west PR, producing
lightning strikes.
There is currently a low risk of rip currents at all beaches in
Puerto Rico and the US Virgin Islands tonight. However, it's
important to note that even with a low risk, life- threatening rip
currents can still occur near groins, jetties, reefs, and piers.
Expect a moderate risk of rip currents returning along the north-
facing beaches on Saturday, spreading to the north and east-
facing beaches in PR and USVI from Sunday onward.
