Area Forecast Discussion
National Weather Service San Juan PR
Issued by National Weather Service MIAMI FL
807 AM AST Sat Sep 23 2017

.AVIATION...
Southeasterly flow will continue, with higher terrain and south
facing slopes of Puerto Rico favored for periodic development of
convection. Satellite imagery indicates a moist air mass in place
with plenty of mid level cloud cover, but VFR conditions expected
to prevail at the terminals, outside of passing scattered showers
and isolated thunderstorms.

&&

.PREV DISCUSSION... /Issued by National Weather Service MIAMI FL/

SHORT TERM...Deep tropical moisture coupled with a south to
southeast flow will keep precipitable water values well over 2
inches through the weekend. Scattered showers with isolated
thunderstorms will persist, and the high precipitable water
values ups the potential for heavy rainfall.

Any additional rainfall that Puerto Rico receives will continue to
aggravate the ongoing flooding on many of the rivers. Also, there
is standing water away from the rivers in many locations as well.
Mudslides have occurred across the island and will likely
continue if additional rainfall is received. Thus, in coordination
with the office in San Juan, we will keep the Flash Flood Watch
up across all of Puerto Rico through 8 am.

It is difficult to ascertain conditions in the area as nearly all
communications links are down. However, some gauges continue to
report. Some river and stream levels are slowly falling but still
remain in flood.

Heat Index values will begin to rise at or above 100 for the
weekend. This will make recovery efforts difficult and overall
living unpleasant as electricity remains out across the island.

LONG TERM...The pattern will change Tuesday into Tuesday night.
Flow will become easterly and precipitable water values will drop
to around 1.75 inches. This will bring more seasonable winds and
relatively drier conditions to the forecast area.

&&

.MARINE...Small Craft Advisories will be discontinued. Showers
and thunderstorms with heavy rain, locally higher winds and waves,
and reduced visibilities will be possible through the weekend.
