...FLASH FLOOD WATCH IN EFFECT FROM MONDAY NOON THROUGH TUESDAY 
EVENING...

The National Weather Service in San Juan has issued a

* Flash Flood Watch for Puerto Rico and the U.S. Virgin Islands
  including Culebra and Vieques

* From Monday noon through Tuesday evening

* There is a high risk for flash flooding across Puerto Rico and
  the U.S. Virgin Islands starting on Monday afternoon through
  Tuesday evening. The passage of an active tropical wave will
  result in periods of heavy shower and thunderstorm activity
  across the region. The bulk of this activity will favor the
  eastern half of Puerto Rico, as well as the U.S. Virgin Islands
  through the period. However, diurnal heating and local effects
  will enhance shower and thunderstorm activity across the
  interior and western sectors of Puerto Rico during the afternoon
  hours.  

Overall, rainfall totals are forecast to range between 2 and 4 
inches with isolated amounts up to 6 inches in Puerto Rico. 
Rainfall totals between 1 and 2 inches with isolated higher 
amounts are expected across the U.S. Virgin Islands. This will
cause guts and small streams to overflow their banks and some larger
rivers to rise above flood stage. Some of these rises will happen
very rapidly when thunderstorms dump heavy amounts in a short 
period of time. There is also a possibility of mudslides in steep
terrain after the first 24 hours of rainfall.

Moisture associated with this tropical wave will continue into
Wednesday with some heavy rains indicated so the the watch will 
be extended if needed on Tuesday.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.

You should monitor later forecasts and be prepared to take action
should Flash Flood Warnings be issued.

* Puerto Rico and the U.S. Virgin Islands.

* From noon AST today through Tuesday evening

* There is a high risk for flash flooding across Puerto Rico and
  the U.S. Virgin Islands starting this afternoon through Tuesday
  evening. The passage of an active tropical wave will result in
  periods of heavy shower and thunderstorm activity across the
  region. The bulk of this activity will favor the eastern half of
  Puerto Rico, as well as the U.S. Virgin Islands through the

Overall, additional rainfall totals are forecast to range between
1 and 4 inches with isolated amounts up to 6 inches in Puerto 
Rico between today and Wednesday. Rainfall totals between 1 and 2 
inches with isolated higher amounts are expected across the U.S. 
Virgin Islands and portions of the coastal municipalities of south
central and southwestern Puerto Rico. This will cause guts and

* Portions of Puerto Rico and Virgin Islands, including the 
  following areas, in Puerto Rico, Central Interior, Culebra, 
  Eastern Interior, Mayaguez and Vicinity, North Central, 
  Northeast, Northwest, Ponce and Vicinity, San Juan and 
  Vicinity, Southeast, Southwest, Vieques, and Western Interior. 
  In Virgin Islands, St Croix and St.Thomas...St. John...and 
  Adjacent Islands. 

* Through Wednesday evening

* There is a high risk for flash flooding across Puerto Rico and
  the U.S. Virgin Islands through Wednesday. The passage of an
  active tropical wave will result in periods of heavy shower and
  thunderstorm activity across the region today and another
  tropical wave will move in on Wednesday. Most of this activity
  will favor the eastern half of Puerto Rico, which will
  exacerbate the flooding that has already occurred across those
  sections. However, significant shower and thunderstorm activity
  is also possible at times across the U.S. Virgin Islands and
  across the south central and southwestern sections of Puerto
  Rico, while the interior and western sections of Puerto Rico 
  would observe most of the activity during the afternoon hours 
  today and on Wednesday.

Overall, additional rainfall totals are forecast to range between
1 and 4 inches with isolated amounts up to 6 inches in Puerto 
Rico between today and Wednesday. Rainfall totals between 1 and 2 
inches with isolated higher amounts are expected across the U.S. 
Virgin Islands and portions of the coastal municipalities of south
central and southwestern Puerto Rico. This will cause guts and 
small streams to overflow their banks and some larger rivers to 
rise above flood stage. Some of these rivers will rise very 
rapidly due to torrential rainfall from thunderstorms in a short 
period of time. There is also a possibility of mudslides in areas 
of steep terrain.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.

You should monitor later forecasts and be prepared to take action
should Flash Flood Warnings be issued.

.A passing tropical wave will continue to produce heavy rains 
across Puerto Rico and the U.S. Virgin Islands this evening. Then,
another tropical wave and its associated moisture will move 
across Puerto Rico and the U.S. Virgin Islands later tonight 
through Wednesday.

Plenty of tropical moisture associated with a passing tropical
wave will continue to spread rain and thunderstorms through this 
evening. Then another tropical wave will bring additional 
rainfall across the local area on Wednesday. Rainfall amounts will
be sufficient to cause or exacerbate flooding in some areas.

  active tropical wave will result in periods of heavy shower and
  thunderstorm activity across the region tonight and Wednesday.
  Most of this activity will favor the eastern half of Puerto
  Rico, which will exacerbate the flooding that has already

  fallen on the eastern flanks of the Luquillo range in Naguabo
  since midnight. Additionally, significant shower and
  thunderstorm activity is also possible at times across the U.S.
  Virgin Islands. Lesser amounts will fall across the south
  central and southwestern sections of Puerto Rico during the
  watch, while the interior and western sections of Puerto Rico
  should observe most of their activity during the afternoon hours on
  Wednesday. 

* Overall, additional rainfall totals are forecast to range
  between 1 and 3 inches with isolated amounts up to 6 inches--
  mainly in eastern in Puerto Rico between tonight and Wednesday.
  Rainfall totals between 1 and 2 inches with isolated higher 
  amounts are expected across the U.S. Virgin Islands and portions

The potential for flooding rain has diminished and is no longer 
expected to pose a threat. However, the previous rains affected
several areas across eastern Puerto Rico and the U.S. Virgin 
Islands and there can still be some ponding of water on roadways.
Be especially cautious at night when it is harder to recognize 
the danger of flooding and please continue to heed any remaining 
road closures.

Area Forecast Discussion
National Weather Service San Juan PR
1127 AM AST Sun Jul 28 2019

.UPDATE...A few showers affected portions of eastern and northern
PR in the morning hours, but have since diminished. The satellite
imagery indicates some cloudiness developing across the higher
elevations of the local islands and streaming to the WSW under
the prevailing ENE wind flow. The latest guidance insists in
shower and thunderstorm development across portions of SW-PR this
afternoon, with isolated to scattered showers elsewhere.

Minor changes were made to the inherited forecast to account for
the increase in moisture and the increase in precip forecast by
the high resolution models. The tropical wave is still expected to
move in late tonight, but some rainfall bands may start moving
into the local waters later this afternoon. Thunderstorms are
being observed with this tropical wave and thus no changes were
made to the forecast for the overnight period since it already
shows a gradual progression of increased shower and thunderstorm
activity.

&&

.AVIATION...VFR conds expected across the local area through
28/17Z. VCSH expected across many of the local terminals for the
rest of today and tonight, but VCTS is expected for TJMZ this
afternoon. As the tropical wave moves in, VCSH/VCTS is to be
expected this evening across TKPK and TNCM, then gradually
approaching TIST and TISX later tonight.

&&

.MARINE...Small craft operators are urged to exercise caution
across the nearshore Caribbean waters of PR due to winds up to 20
knots. Seas will be up to 5 feet the rest of today and tonight,
increasing on Monday as the tropical wave approaches. Showers and
thunderstorms associated with the tropical wave will affect the
local waters starting tonight.

.PREV DISCUSSION... /issued 440 AM AST Sun Jul 28 2019/

SYNOPSIS...Light passing showers early this morning should brush
the northern coast of PR and the USVI. Diurnally induced
afternoon convection will follow over west/southwest PR. Shower
and thunderstorm activity will increase from Monday through
Wednesday due to the passage of two tropical waves. Another wave
is expected on Friday. Hazy skies due to Saharan dust return
briefly on Thursday and once again during the weekend.

SHORT TERM...Today through Tuesday...

A fairly stable weather pattern is expected to prevail across the
area for today as a drier than normal air mass remains in place.
However, patches of low-level moisture embedded within the easterly
trade wind flow will continue to move across the area from time to
time through this afternoon. This will result in some passing
showers across portions of northern and eastern Puerto Rico through
the early morning hours, followed by the development of showers and
isolated thunderstorms across western Puerto Rico during the
afternoon hours as the low-level moisture combines with the strong
daytime heating and sea breeze convergence. In terms of the Saharan
dust concentration, the good news is that the concentration will be
much lower today compared to previous days.

Attention will then turn to a vigorous tropical wave, currently
located over the Lesser Antilles, that will be approaching the area
tonight. Moisture will increase in earnest starting this evening
across the USVI and later during the overnight hours across eastern
Puerto Rico. Latest model guidance indicates precipitable water
values increasing to as high as 2.30 inches, which is around 2
standard deviations above normal for July. Therefore, conditions
will be favorable for the development of deep and organized
convection. Showers and thunderstorms are expected to increase in
coverage across the USVI later this evening and across eastern
Puerto Rico during the overnight hours. Then, during the day on
Monday, widespread showers and thunderstorms are expected to affect
the local area with activity expected to cluster across the USVI and
eastern Puerto Rico during the morning hours and then extend into
western Puerto Rico into the afternoon hours. The potential will
exist for urban and small stream flooding as well as rapid river
rises and mudslides in areas of steep terrain across areas that
receive a prolonged period of heavy rainfall activity.

The unsettled weather conditions will continue into Tuesday as
precipitable water values continue to remain above 2.0 inches. The
low-level flow will become southeasterly. Therefore, activity is
expected to cluster across portions of southern and eastern Puerto
Rico and the USVI during the morning hours. Then, depending on the
amount of sunshine that develops, additional activity is expected
across the northwest quadrant of Puerto Rico during the afternoon
hours. Once again, urban and small stream flooding as well as rapid
river rises and mudslides in areas of steep terrain will be a
concern.

Generally speaking, this tropical wave that will be affecting the
area during the first part of the work week promises to bring
beneficial rains to areas that have been suffering from significant
drought conditions during the last several weeks to months.

LONG TERM...Wednesday through Sunday...

Another tropical wave streams quickly on Wednesday, the flooding
threat will remain high due to saturated soils from the previous
days heavy rainfall. Models indicate high precipitable water
content across the USVI/Eastern sections of PR between the
morning and afternoon hours. A drier air mass with Saharan dust
filters after the wave passage, creating hazy skies and fair
weather conditions through Thursday. However, diurnally induced
afternoon showers can not be ruled out over western PR. By Friday,
another tropical wave but not as vigorous as the previous waves
will bring scattered showers and isolated thunderstorms across the
region. Breezy conditions and another drier air mass with Saharan
dust are expected to prevail during the weekend. Although moisture
decreases during the weekend, the combination of the available low
level moisture, daytime heating and sea breeze convergence will
result in showers and possible isolated thunderstorms over the
western sections of PR each afternoon.

AVIATION...Mainly VFR conditions to prevail through most of the
period. SHRA/TSRA expected across western PR between 28/16z and
28/22z, affecting mainly the vicinity of TJMZ. TEMPO MVFR conditions
are possible. A tropical wave will bring an increase in SHRA/TSRA
activity across the Leeward Island terminals after 28/21z and across
the USVI terminals after 29/00z. Winds light and variable through
28/13z, increasing to 10 to 20 kts with higher gusts and sea breeze
variations after 28/14z.

MARINE...Seas will continue at less than 5 feet and east-
northeast trades should range between 10-15 knots today. However,
winds up to 20 knots are possible across the Caribbean coastal
waters of PR and small crafts should exercise caution across these
waters. Squally weather is expected from Monday through Wednesday
due to the passage of two tropical waves. Choppy seas are
expected to prevail across most of the regional waters and small
crafts should exercise caution. There is a moderate risk of rip
currents mainly for the north/northwest beaches oh PR and St.
Croix.

...Active thunderstorms still have potential to generate
landspouts...

At 206 PM AST, thunderstorms stretched from Cabo Rojo to Penuelas
and southern Adjuntas. The thunderstorms were drifting slowly west
southwest.

The strongest area was over Punta Guanaquilla. One funnel has been
reported to the National Weather Service although it had not yet
touched the ground.

Conditions in the atmosphere are such that weak, brief funnels may
form this afternoon. They usually develop beneath showers or weak
thunderstorms when the air aloft is especially cold or the surface
is especially warm.

These funnels are usually harmless, but on rare occasions can briefly
touch down and cause wind gusts over 50 mph. If a funnel approaches
your location, move indoors.

Please contact the National Weather Service if you see a funnel.
