...FLASH FLOOD WATCH IN EFFECT FROM 6 PM AST THIS EVENING THROUGH
FRIDAY EVENING...

The National Weather Service in San Juan has issued a

* Flash Flood Watch for a portion of Puerto Rico, including the 
  following areas, Central Interior, Eastern Interior, 
  Northeast, Ponce and Vicinity, San Juan and Vicinity, and 
  Southeast. 

* From 6 PM AST this evening through Friday evening

* As the outer bands of Tropical Storm Isaac move closer to the
  forecast area, showers and thunderstorms with some gusty winds
  will begin to affect the local islands as early as late tonight
  into early Friday morning. The shower and thunder activity is
  expected to become more frequent by the mid morning hours on
  Friday and continue through at least Friday night. 
  
 Although fast-moving showers and thunderstorms are anticipated, 
 the rainfall activity could be enhanced by the local terrain. 
 Based on the latest forecast and the complexity of the terrain, 
 rainfall totals will range between 2 to 4 inches with locally
 higher amounts possible across the south central, southeast and 
 east sections of Puerto Rico. As a result, there is a moderate 
 to high risk of flash flooding across these areas, and a Flash 
 Flood Watch has been issued. 
 
 Possible impacts include, flooding of rivers and small streams 
 as well as mud slides in areas of steep terrain. 

 Elsewhere, including Vieques, Culebra, Saint Thomas and 
 Saint Croix, lower rainfall accumulations are expected. Rainfall
 totals will range 1 to 2 inches and therefore the risk for flash
 flooding across western Puerto Rico and the outlying islands is 
 low. However, urban flooding is still possible.

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.

  However, additional rainfall amounts between 1 and 2 inches are
  still possible across southeast Puerto Rico overnight. Although
  the latest observations from USGS river gauges suggested rivers

  levels, sharp rises along rivers, small streams and creeks 
  cannot be ruled out with the additional rainfall activity.
 
 As a result, the Flash Flood Watch has been extended through the

...FLASH FLOOD WATCH IS CANCELLED...

The Flash Flood Watch for portions of Puerto Rico, including the 
Central Interior, Eastern Interior, Northeast, Ponce and Vicinity,
San Juan and Vicinity, and the Southeast has been cancelled. As 
the trailing moisture and much of the heavy shower activity associated
with Tropical storm Isaac continued to move westward and away from
the from Puerto Rico during the early morning hours, the potential
for widespread Flash flooding has diminished. In addition recent river
sensors and gages continued to indicate that water levels along 
rivers and streams were now below flood stage and continued to 
subside. No additional widespread heavy rains is expected for the 
moment. Therefore the Flash Flood Watch for portions of Puerto 
Rico has been cancelled. However, during the rest of the day 
periods of moderate locally heavy rains will remain possible in 
isolated areas across portions of the island. This may lead to 
minor flooding along rivers and small streams and in urban and 
poor drainage areas. Mudslides will also remain possible in areas 
of steep terrain due to saturated soil.

Area Forecast Discussion
National Weather Service San Juan PR
443 AM AST Thu Sep 13 2018

.SYNOPSIS...Building high pressure ridge north of the region and Tropical
Storm Isaac will continue to dominate the local synoptic pattern across
the region through Friday as Tropical Storm Isaac passes south of the
forecast area. Small infrequent bands of low clouds and showers generated
from the distant Tropical storm Isaac will make its way across the
local region and bring periods of moderate to heavy rains and gusty
winds across the coastal waters and parts of the islands during the
rest of the morning. A fairly moist and unstable weather pattern is
forecast through most of the week and into early next week with winds
becoming more southeasterly by Friday and into the weekend.

&&

.SHORT TERM...Today through Saturday...

Isaac's forward outer band will continue to stream across the region
through this evening. This will feed squally weather conditions
along with gusty winds across the forecast area. First, streamer-
like scattered to numerous showers will quickly move across the
waters and into coastal areas of northern and eastern Puerto Rico
and the U.S. Virgin Islands during the early morning hours, then
these showers will affect the rest of the forecast area during the
late morning and early afternoon hours as this band progress
westward. The moisture associated to this band in combination with
diurnal and local effects will trigger afternoon convection over
most of Puerto Rico, with the strongest activity focused over the
interior and southwestern portions of the island.

Following the departure of the aforementioned outer rain band,
occasional rain bands will quickly move across the forecast area.
Although a slight break in showers and thunderstorm activity can be
expected, a secondary event of showers and thunderstorms is expected
as Isaac approaches and moves south of the local islands late
tonight into Friday. Showers and thunderstorms will first affect the
U.S. Virgin Islands and the eastern half of Puerto Rico during the
overnight hours. As the storm progress westward, the coverage and
intensity of the activity will increase, affecting most of the local
islands and waters through late Friday night. Based in the current
forecast, total rainfall accumulations are expected to range between
1 and 2 inches with isolated amounts up to 4 inches between today
and Saturday. Thus, urban and small stream flooding, rapid rises
along rivers, and mudslides near steep terrain are highly likely
during this forecast period.

Lingering moisture from Isaac will remain over the forecast area on
Saturday, resulting in a relative seasonal pattern. That is, showers
streaming over the waters into coastal areas of southern and eastern
Puerto Rico during the overnight and early morning hours, followed
by afternoon convection over the interior and western Puerto Rico.
The potential for urban and small stream flooding remains possible
on Saturday.

.LONG TERM...Sunday through Friday...
Following the passage of Isaac south of the region, a moist
southeasterly flow is expected to prevail through most of the
upcoming weekend and into early next week. Recent model guidance
continued to suggest layered precipitable water values in excess
of 2 inches into early next week. The proximity of a retrograding
Tutt low and another tropical wave forecast to move across the region
during the early part of next week will maintain a moist and unstable
environment trough at least Wednesday, with a gradual improvement
during the latter part of the week. The overall pattern should therefore
support periods of moderate to heavy rainfall with showers and isolated
thunderstorm activity each day at least through mid week followed by
lesser potential for shower development and drier conditions expected
thereafter.

&&

.AVIATION...VFR conditions will prevail across area airports for most
of the forecast period. However, there are chances for isolated
passing showers through the mid morning hours along the northern
coasts facing terminals. Model guidance bring a drier airmass across
the area for the first part of the afternoon and therefore, limited
shower activity is anticipated with the exception of the typical
afternoon convection over TJMZ around 21Z to 00Z FRI. Cigs of SCT020-
030 with a second cloud deck of SCT030 to BKN40 are expected across
the area through the forecast period. E to NE winds of 5 to 15 knots
and gusts up to 20 knots are expect for this cycle.

&&

.MARINE...Seas at buoy 41044 have ranged between 8 to 10 feet, while
the northern buoy 41043 was around 7 feet overnight through the early
morning. These wind generated waves and north and east swell action
is expected to spread across the regional waters and passages through
Friday bringing deteriorating and hazardous sea conditions. Winds
and seas are forecast to increase and reach 8 to 10 feet through Friday
with occasional seas up to as much as 12 feet over the offshore Caribbean
waters and the Anegada passage. Occasional gusts and squalls will remain
possible across the local waters in advance of the tropical storm as
it is still forecast to pass south of the region. Small craft advisories
will therefore eventually be required for most of the local waters and
passages beginning today and continuing through Friday. Please refer
to the latest Coastal Waters Forecast and Marine Weather Message issued
by the National Weather Service WFO San Juan PR.
