NWS San Juan, PR wrote its last area forecast discussion before the first event at Jul 10, 1:20 PM AST, 2 hours 10 minutes earlier.
Area Forecast Discussion National Weather Service San Juan PR 120 PM AST SUN JUL 10 2016 .SYNOPSIS...Tropical wave is moving across the Eastern Caribbean today. Although showers and thunderstorms will affect the islands this afternoon and evening...the bulk of the convection will remain over the Caribbean Waters. Stable pattern with a pulse of Saharan dust is forecast in the wake of the tropical wave. No significant changes in the weather pattern is expected the rest of the work week. && .DISCUSSION...Satellite loops show the best convection associated with the tropical wave well south of the local area. Moisture in the northern periphery of the wave is inducing the development of scattered showers across the local area. Later this afternoon... stronger showers and a few strong thunderstorms are still possible over the northern half of Puerto Rico due to the interaction of the wave and the orographic effects. Conditions will gradually improve late tonight as the tropical wave moves away from the forecast area. Mid level high pressure will maintain a stable pattern across the local islands most of the work week. Early in the week...Aerosol models...NASA GEOS-5 and NAAPS indicate a pulse of Saharan Dust moving across the region. This dusty air mass will produce hazy skies and somewhat reduced visibilities. The relatively dry and subsidence air mass at mid levels of the atmosphere will also limit the development of showers across the local region through midweek. Although...afternoon showers can not ruled out the coverage over western PR will be mainly isolated or locally scattered. No significant weather feature is foreseen the rest of the work week. Synoptic models suggest better moisture the next weekend when a tropical wave moves across the local region. && .AVIATION...SHRA/TSRA possible later this afternoon with brief MVFR conds and BKN-OVC cigs btw FL025-FL070 at TJBQ/TJSJ/TJMZ thru at least 10/23z. Sfc winds from the east at 10-20 kt with sea breeze variations and higher gusts in/near SHRA/TSRA. && .MARINE...Winds of 15-20 knots and seas to 4-6 feet expected through late tonight. Winds and seas will gradually subside through midweek. Overall seas of 3-5 feet and winds of 10-15 knots can be expected most of the week. No Small Craft Advisories anticipated this week. && .PRELIMINARY POINT TEMPS/POPS... SJU 77 90 78 89 / 50 10 20 20 STT 78 91 79 90 / 30 20 30 20 && .SJU Watches/Warnings/Advisories... PR...None.
