Area Forecast Discussion
National Weather Service San Juan PR
910 PM AST Sun Oct 25 2020

.UPDATE...Trade wind showers are expected to affect portions of
eastern PR and the USVI from to time throughout the night into
the early morning hours of Monday due to a surge in low-level
moisture. Given the fast movement of these showers, rainfall
accumulations should remain limited. Afternoon shower development
is expected across western Puerto Rico with isolated thunderstorms
possible as well. Later tomorrow night into Tuesday, deeper
moisture associated with the arrival of a tropical wave is
expected, resulting in more frequent shower activity with rainfall
accumulations expected to be more significant.

&&

.AVIATION...Mainly VFR conditions expected across the terminals
areas. However, passing SHRA at times will result in VCSH across
the eastern PR, USVI, and Leeward Islands terminals. No
significant impacts to operations expected at this time. SHRA and
isolated TS possible across western PR between 26/16z and 26/22z,
possibly affecting the vicinity of TJMZ. Winds are expected to
be less than 10 kts overnight, increasing to 15 to 20 kts with
gusts to near 25 kts at times with sea breeze variations after
26/14z.

&&

.MARINE...Some significant adjustments were made to the marine
grids as the outer buoy is currently reporting a wave height of 8
feet with a 14 second period. This is due to a northerly swell
originating from Tropical Storm Epsilon, located over the north-
central Atlantic. This swell is expected to arrive into our local
waters overnight. This will result in hazardous seas of up to 8
feet across most of the local waters with breaking wave heights of
up to 12 feet across the northern coast of Puerto Rico and
Culebra. Small craft advisories are in effect for most of the
local waters. High surf advisory is in effect for the northern
beaches of Puerto Rico and Culebra starting at 4 AM AST Monday and
continuing through early Tuesday Morning. High Rip Current Risk
is also in effect for most of the northern beaches of the islands
as well.

&&

.PREV DISCUSSION... /issued 412 PM AST Sun Oct 25 2020/

SYNOPSIS...

The chance for shower activity across the local islands is
expected to increase during the workweek under troughiness and
moisture advection. Rough seas are expected much of this week.

SHORT TERM...Tonight through Tuesday...

Short term forecast is still on track. Ridge aloft will continue
to weaken during the next few days as troughiness develops east
of the area. At lower levels, a surface high across the central
Atlantic will continue to yield moderate to fresh east to east
northeast winds through at least midweek. A tropical wave located
near 50W is expected to reach the eastern Caribbean Tue-Wed. The
troughiness aloft and the approaching tropical wave will promote
moisture advection during the forecast cycle, with precipitable
water values reaching 2.0 inches by Tuesday afternoon.

As a result, continue to expect mostly fair weather conditions
tonight. However, we will trend toward wetter conditions Monday
onwards. Passing showers across eastern Puerto Rico and the US
Virgin Islands, as well as showers and thunderstorms developing
across western areas of Puerto Rico in the afternoon are expected
Monday and Tuesday. This will increase the potential for urban and
small stream flooding.

LONG TERM...Wed through Mon/issued 443 AM AST Sun Oct 25 2020...

Wednesday continues to look wet as a surge of moisture is expected
to arrive associated with an old tropical wave. The moisture will
arrive early in the morning which will likely kick off scattered
showers across the eastern Puerto Rican coastal areas and over the
USVI. Then in the afternoon, the showers will shift to western and
southwestern Puerto Rico under winds between 925 and 700 mb of
around 20 to 25 knots from the ENE. These brisk winds will cause
quick moving showers to help limit rain accumulations. Upper-level
conditions are a bit uncertain, since long-range models are showing
different solutions. However at this point, conditions do not look
overly favorable for strong thunderstorms, but isolated
thunderstorms are likely. This will be closely monitored however,
since there will be troughing at least in the vicinity that could
enhance activity for Wednesday.

Though long-range models seem to disagree about how the upper-level
conditions will play out, there does not appear to be any day in the
long term period where upper-level troughing would act to really
enhance activity. Furthermore, strong high surface pressure is
expected to continue in the central Atlantic during the long term
period, which will keep brisk low-level winds in place to limit
rainfall accumulation. Plentiful moisture will still be in place
for Thursday and Friday with winds more from the ESE, which will
produce showers and isolated thunderstorms for northwestern PR in
the afternoon. Scattered showers are possible in the overnight and
morning hours for both days. Heading into the next weekend,
models again disagree on how wet those days will be. It appears we
will be near a gradient of high moisture to our south and dry air
to our north, thus it is difficult this far out to determine the
weather for those days.

504 AM AST domingo 25 de octubre de 2020

Esta perspectiva sobre las condiciones peligrosas del tiempo es para
Puerto Rico y las aguas costeras del Atlantico.

.Dia Uno...Hoy y esta noche

.Tronadas...Existe el potencial de tronadas aisladas con lluvia
fuerte y vientos en rafaga breves esta tarde a traves de sectores del
oeste interior de Puerto Rico.

.Inundaciones...Lluvias fuertes pudieran resultar en inundaciones
urbanas y de riachuelos, al igual que en acumulacion de agua en
carreteras y areas de poco drenaje.

.Viento...Se esperan vientos localmente mas altos en exceso de 20
mph (17 nudos) con rafagas ocasionalmente mas altas a traves de las
aguas costeras del norte y sur de Puerto Rico.

.Oleaje...Se espera oleaje picado de hasta 6 pies a traves
de las aguas adjacentes y los pasajes locales de las
islas...tornandose peligroso hasta 7 pies temprano esta noche.

.Corrientes marinas...Existe un riesgo alto de corrientes
marinas para las costas del norte de Puerto Rico y Culebra, y un
riesgo moderado para la mayoria del resto de las playas,
al igual que para las playas de Vieques.

.Calor...Vientos alisios del este sureste resultaran en indices de
calor por encima de lo normal especialmente a lo largo de areas
costeras del norte y este, incluyendo Culebra y Vieques.

.Dias dos hasta el siete...lunes a sabado

Un aumento en la humedad tropical a traves del area de pronostico
desde martes y adelante resultara en un mejor potencial de
desarrollo de aguaceros y tronadas sobre y alredador de las islas.
Una marejada del norte y un aumento en los vientos alisios causara
el deterioro de las condiciones maritimas una vez mas hasta por lo
menos mediados de la semana. Esto resultara en oleaje picado y
peligroso. Un riesgo moderado a alto de corrientes marinas
continuara hasta el miercoles para las playas expuestas hacia el
norte e incluira las playas de Culebra y Vieques hasta jueves.
