NWS San Juan, PR wrote its last area forecast discussion before the first event at May 14, 2:59 PM AST, 1 hour 21 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service San Juan PR 259 PM AST Wed May 14 2025 .KEY MESSAGES... * Breezy wind conditions will maintain choppy to rough seas and a moderate risk of rip currents through at least the end of the workweek. * A wet and unstable weather pattern is expected to develop by the end of the workweek and persist into the weekend, increasing the risk of flooding across Puerto Rico and the U.S. Virgin Islands, particularly on Friday and Saturday. * Additionally, suspended Saharan dust particulates will move into the region, resulting in hazy skies in areas with limited rainfall activity. && .SHORT TERM...Tonight through Friday... Variable weather conditions were observed across the forecast area this morning. As anticipated, moisture has already begun to gradually increase, as shown by the 12Z sounding, which indicated 1.73 inches of precipitable water—0.29 inches more compared to yesterday at the same time. As a result, persistent passing showers moved through the area; however, no significant accumulations were recorded during the morning because strong east-southeast winds moved the showers fairly quickly. Based on radar estimates, rainfall totals remained below 0.25 inches across most of the area. After midday, slightly stronger showers developed across the northern and western parts of Puerto Rico, producing around one inch of rain. As of 1 PM AST, daytime high temperatures generally ranged from the low to mid-80s °F, but surface observations registered even low 90s °F in low-elevation and urban areas of southern Puerto Rico. For the rest of the afternoon, rain is expected to remain localized over western and northwestern parts of Puerto Rico and the interior. Tonight, generally calm conditions should dominate, though additional showers will move in with the trade winds across the U.S. Virgin Islands and eastern Puerto Rico. The forecast remains generally on track for the coming days. A gradual transition to a wetter and more unstable weather pattern is expected through the end of the week. An upper-level trough approaching from the west-northwest will increase instability, especially toward the end of the week. Additionally, a surge of tropical moisture will lead to above-normal moisture levels beginning Thursday afternoon and evening onward. Temperatures at 500 mb will drop to around -8°C, creating favorable conditions for periods of moderate to heavy rainfall and thunderstorm development. The main uncertainty right now is the possible future presence of Saharan dust and cloud cover, which could limit some convective development. However, the overall risk of urban and small stream flooding, and potentially isolated flash flooding, remains in place. A Hydrologic Outlook was issued today and Friday and Saturday have and elevate to significant food threat. The main takeaway is that there is a moderate chance (40–60%) of receiving 2 to 4 inches of rain, with locally higher amounts of up to 6 inches each day across southeastern and eastern portions of Puerto Rico, as well as Vieques, Culebra, and the U.S. Virgin Islands. Elsewhere, rainfall totals could exceed 1 to 2 inches. Due to already saturated soils and rivers and tributaries running well above normal levels, the risk of flooding is increasing across Puerto Rico and the U.S. Virgin Islands on Friday and Saturday. Residents, visitors, and local officials are encouraged to stay informed and monitor forecast updates as we approach the weekend and uncertainty decreases. .LONG TERM...Saturday through Wednesday... A wet and unstable weather pattern is forecast Saturday through early next week. A deep layered trough, currently over the western Caribbean and western Atlantic, will gradually move eastward towards the local islands, this feature will promote more favorable conditions for widespread shower and thunderstorm activity during the weekend. A surface trough will also develop, also providing instability and promoting, along with a surface high over the central to eastern Atlantic, light east- southeast to southeast surface flow over the region to start the period. These features will converge with deep tropical moisture that will also be over the region and will continue to arrive from the east- southeast, with current model guidance showing a completely moist atmospheric profile, possibly being somewhat confined to below 500mb by late Sunday and into early next week. By Saturday, current model guidance continues to indicate precipitable water (PWAT) values around 2.25 inches over the islands, above normal values for this time of the week. A slight decrease in PWAT values is forecast at times during the period but will increase again to around 2 inches. A limiting factor for this activity could be Saharan Air Layer that could also reach the islands this weekend. Although PWAT values will continue to be elevated, the deep layer troughs influence will not be as pronounced Tuesday and Wednesday. Widespread showers and thunderstorms are forecast particularly over the eastern region and interior PR and with already saturated soils and elevated streams, there is an increased risk of urban and small stream flooding, flash flooding, river rises and debris flow in steep terrains. Up to an elevated flooding risk is forecast during these days. Further monitoring will continue and a significant flooding threat may be added and a Hydrologic Outlook may be issued soon, a Flash Flood Watch is also possible. Stay tuned for any updates. && .AVIATION... (18Z TAFs) Areas of SHRA/TSRA are expected with brief MVFR/IFR conds psbl at TJBQ/TJSJ and mtn topping in W/NW and interior PR through 23z. Sfc ESE winds of 10-18 kts with gusts to 25-28 kt psbl. Winds subsiding to arnd 10 kts aft 14/22Z. && .MARINE... A broad surface high pressure over the Central Atlantic will continue to result in moderate to fresh easterly winds that will result in choppy and rough seas across the offshore waters. A Small Craft Advisory is in effect for the Offshore Atlantic and Anegada Passage through at least this evening due to seas of up to 6 to 7 feet. Small Craft Should Exercise Caution over most of the other local waters. A deep trough will promote an unsettled weather pattern with a high chance for thunderstorm development from Thursday afternoon onward, resulting in locally higher winds and seas. && .BEACH FORECAST... Life-threatening rip currents are possible along most northern and eastern exposed beaches of the islands. The risk is expected to gradually diminish this weekend as winds subside. For more details, please refer to the latest Coastal Hazard Message (CFWSJU) and Surf Zone Forecast (SRFSJU). Shower and thunderstorm activity is likely to increase by the end of the week and continue into the weekend as we transition back to a wet and unstable weather pattern. Reminder: Seek shelter and leave the water or beach at the first sign of thunder or lightning. && .SJU WATCHES/WARNINGS/ADVISORIES... PR...None. VI...None.
