National Weather Service San Juan PR
203 PM AST Wed Feb 15 2017

.SYNOPSIS...Upper level ridge will continue to dominates the local
area through the weekend. A very week frontal boundary will stay

.DISCUSSION...Once again, a very dry air prevailed across Puerto

shower activity was observed across the local islands. Local area
will continue to be dominated by a upper level ridge which will
promote very dry weather conditions across the local area through
the rest of the week and beyond.

A very weak frontal boundary will continue to move slowly
southeast across the western Atlantic. This front will stay north
of the area while weakening. It is not until early next week,
another frontal boundary will it is expected to approach the
local region, increasing somewhat the chances for showers across
the region.

&&

.AVIATION...Mostly VFR conditions are expected to prevail through the
forecast period across the local flying area. Due to east southeast
low level wind flow, MVFR conditions are possible in and around TJBQ
due to SHRA until 15/22Z. Latest TJSJ sounding indicated a light
wind flow all the way from the surface to around 12K feet, becoming
northwesterly and stronger aloft.

northerly swell invade the local waters. No changes were made to
marine forecast grids.

Guayama around 1 pm AST this afternoon. As a very dry airmass will
continue across the region, Fire Danger will continue to increase

weather conditions are becoming more conducive for the ignition
and spread of wild fires.
