NWS San Juan, PR wrote its last area forecast discussion before the first event at Mar 22, 4:45 AM AST, 9 hours 15 minutes earlier.
Area Forecast Discussion National Weather Service San Juan PR 445 AM AST Sat Mar 22 2025 .SYNOPSIS...A cold front currently positioned over the Bahamas and extending northward will gradually move eastward across the Atlantic. As it progresses, the front is expected to weaken, losing much of its intensity by the time it approaches our local region. While the front may bring some subtle changes in wind patterns and a slight increase on cloud cover, significant weather impacts are unlikely due to its weakening state. && .SHORT TERM...Today through Monday... During the overnight hours, winds increased and gradually shifted toward a more easterly component. This shift enhanced land-breeze convergence along the northern coast of Puerto Rico and around St. Thomas, supporting the development of scattered to locally numerous showers across these areas.Portions of the NE Puerto Rico including the San Juan metro area experience localized moderate to heavy rain for briefed periods. Moisture levels are expected to continue rising through the rest of today, supporting the development of shower activity, particularly across western Puerto Rico during the afternoon hours. The forecast highlights a potential risk of excessive rainfall, with localized urban and small stream flooding possible mainly during the afternoon hours over the western portions of Puerto Rico. On Sunday, drying trend will begin to take hold across the region. While isolated to scattered showers are still possible during the afternoon hours, they will be more limited in coverage and intensity compared to today. By Monday, a high pressure ridge will build over the local area making it more stable with reducing significantly the showers and cloud coverage across the local forecast area. .LONG TERM...Tuesday through Saturday... Patches of moisture, with precipitable water values (PWAT) at around 1.5 in or more, will move over the region to start the long term period, under east to east-southeast steering flow. A strong surface high will be in place by Tuesday and will continue to promote up to breezy wind flow. A mid to upper level ridge will also be present Tuesday through early Thursday promoting more stable and drier conditions aloft, with available moisture mostly contained below 700 mb. The start of the period will be characterized by the general diurnal pattern, with overnight and morning trade wind showers moving over windward sectors of the islands and afternoon convective showers mainly over west-northwest Puerto Rico due to diurnal heating, sea breeze convergence and local effects. Moisture and instability increase somewhat to end the period, as a mid to upper trough moves over the region Friday and Saturday. PWAT values will also increase to at or above 1.5 in over the islands as a frontal boundary or its remnants move over the region. These factors can help boost the diurnal pattern late in the workweek and into the weekend. The steering flow is forecast to back and become more northeasterly by late Saturday. 925mb temperatures will be at normal to above normal values to start the period. && .AVIATION... SHRA may bring brief periods of VFR conditions at TJSJ through the period, USVI terminals after 22/06, and TJBQ between 22/16Z- 22/20Z. ENE winds at 5 to 10 knots will increase to 10 to 15 knots with higher gusts after 22/14Z. && .MARINE...The large northerly swell that affected for the past few days will continue to slowly subside today. As winds continue to shift to an easterly direction and strengthen, reaching speeds of 15-25mph, wind related hazards along the coastal areas are expected. Therefore expect choppy seas, hazardous marine conditions, and an elevated risk of rip currents. && .BEACH FORECAST...Although the large swell that impacted the local waters over the past few days will continue to subside today dangerous rip current conditions are expected to persist. This is due to increasing winds across the local region, which will maintain hazardous coastal and marine conditions. Beachgoers and swimmers should exercise extreme caution, as strong rip currents can pose a significant risk to even the most experience individuals. && .FIRE WEATHER...RH values should remain near or above critical levels today across the region. Wind speeds will remain below critical levels, with sea breezes influencing the coastal areas. Therefore, there is a low fire danger today but we will continue to closely monitor any changes to see if conditions warrant. && .SJU WATCHES/WARNINGS/ADVISORIES... PR...High Rip Current Risk through this afternoon for PRZ001-002-005- 008-010-012. VI...High Rip Current Risk through this afternoon for VIZ001. AM...None. && SHORT TERM...EM LONG TERM....MRR AVIATION...EM
