NWS San Juan, PR wrote its last area forecast discussion before the first event at Sep 14, 1:53 PM AST, 3 hours 37 minutes earlier.
Area Forecast Discussion National Weather Service San Juan PR 153 PM AST WED SEP 14 2016 .SYNOPSIS...A mid to upper level ridge will continue to build across the eastern Caribbean, as TUTT continues to move west and away from the local islands. Ridge aloft is then expected to hold through early the upcoming weekend. As this feature erodes, trofiness will return to the forecast area early next week. A gentle to moderate easterly wind flow will prevail across the forecast area during the next few days. && .DISCUSSION...Mostly sunny and rain-free conditions prevailed across the forecast area this morning. Locally induced showers and thunderstorms developed over and W of Cordillera early this afternoon. A mostly fair and stable weather pattern will prevail across the local islands through early the upcoming weekend under ridge aloft and limited low level moisture. Although a trough aloft is expected to amplify across the area Sat-Sun, local islands will remain under it convergent side. Therefore fair weather still expected Sat-Sun. A few locally induced afternoon showers and thunderstorms still possible each day. As the trough axis relocates to our west, moisture advection is expected across the forecast area early next week. Therefore there is a better chance for showers with thunderstorms across the forecast area Mon-Wed. && .AVIATION...VFR conds expected across most of the forecast area. However...brief MVFR conds and mountain obscurations are likely in and around TJMZ through 22Z. VCTS possible near TJPS and TJBQ with the afternoon convection. NE to E winds at 10 kt are expected to prevail fm SFC to FL100. && .MARINE...Tranquil marine conditions expected to prevail across the local islands during the next few days...with winds 10-15 kt and seas 3-5 feet across most of the waters. && .PRELIMINARY POINT TEMPS/POPS...
