.SYNOPSIS...
Issued at 518 PM AST Fri Oct 27 2023
A Flash Flood Watch remains in effect for Puerto Rico and the United
States Virgin Islands through Monday morning. Unsettled conditions
are expected to persist with showers and scattered thunderstorms
affecting the islands. The risk of urban, river, and flash flooding,
as well as mudslides will be elevated through at least early next
week.
&&
.SHORT TERM...Tonight through Sunday...
A wet and unsettled weather pattern will continue through at least
early next week. Therefore, a Flash Flood Watch is in effect through
Monday morning. Currently, the bulk of the activity is affecting the
western and southern municipalities of Puerto Rico with more
isolated across the rest of the island. Convective activity is also
developing over the waters close to Vieques, Culebra, and USVI.
Several Flash Flood Warnings have been issued with many reports of
flooded roads and some wind damage throughout the afternoon.
The main feature during the short-term forecast is an upper-level
trough, a pre-frontal trough, and remnants of the tail from now
Tropical Storm Tammy affecting the local area. Favorable dynamics
and deep tropical moisture will continue to be advected from the
south for the rest of the short-term forecast. According to the
surface analysis from the Tropical Analysis & Forecast Branch
(TAFB), the surface trough will continue to be positioned east of
Puerto Rico tomorrow, and eventually move west of Puerto Rico. Due
to the extensive period of rain expected, as well as the rain
received during the past few days, a Flash Flood Watch was issued
for all of Puerto Rico and the United States Virgin Islands. An
enhanced risk for urban, river, and flash flooding, as well as
mudslides, will persist. There are some discrepancies in the global
models with the timing, location, and amounts expected. However, the
users are advised to stay tuned for further updates to the forecast,
as adjustments may be needed.
.LONG TERM...Monday through Friday...
The GFS model continues to suggest that a wet and unstable weather
pattern will continue through Thursday while the ECMWF model
continues to suggest improved weather conditions by Tuesday. Because
of this, uncertainty remains in the long term forecast. The GFS
model suggests precipitable water (PWAT) values at around and above
2.5 inches across the region to start the workweek, decreasing
somewhat to around 2.2 inches on Tuesday before drier air filters
in on Thursday and Friday. A surface trough will persist over the
area with additional tropical waves arriving from the east.
Southerly flow will persist over the area through Thursday,
helping to lift tropical moisture into the area from the ITCZ
before drier air from the east arrives on Thursday. To start the
period, a mid to upper level ridge will be overhead, with the
upper level trough mentioned in the short term period lifting to
the northeast and away from the region. Although the environment
will remain moist, the driving force for the afternoon convection
will be diurnally induced, as conditions will be more stable
aloft, with additional instability from the lingering surface
trough. Model guidance suggest a mid to upper level trough
building to our east slowly eroding the ridge throughout the
period. Overall, a wet and unstable pattern is forecast at least
through Tuesday with urban and small stream flooding likely and,
with saturated terrain, the potential for flash flooding and
mudslides in areas of steep terrain, uncertainty in the forecast
increases by Wednesday onwards. Please continue to monitor future
updates.
