000 AWCA82 TJSJ 182051 RWSPR PRZ001>013-190900- Weather Summary for Puerto Rico National Weather Service San Juan PR 451 PM AST Mon Oct 18 2021 Mostly sunny skies became partly cloudy to variably cloudy during the afternoon, as showers and isolated thunderstorms developed across the interior and southern slopes of Puerto Rico. This lead to periods of locally heavy rainfall and consequently minor urban and small stream flooding in some areas. Estimated rainfall accumulations were between 1 to 2 inches with the heaviest rains. Winds were generally light but from the east to northeast at 5 to 10 mph with sea breeze variations. Daytime high temperatures were in the upper 80s to near 90 degrees along the coastal areas, and in the upper 70s to low 80 in higher elevations and valleys. Skies will become mostly clear to partly cloudy across the islands with only limited passing showers expected to reach some of the north and east coastal areas from time to time. Overnight low temperatures will be in the mid to upper 70s along coastal areas, and in the upper 60s at higher elevations. Winds will be calm to light and variable. A mixture of sunshine and clouds is expected once again on Tuesday with again the chance for locally and diurnally induced afternoon convection mainly over the interior and west to southwest sections of Puerto Rico. Seas will remain tranquil across the local waters, at 3 feet or less overnight into Tuesday. Light to gentle winds from the east to northeast between 5 to 10 knots will prevail. There is a low risk of rip currents across the local beaches. $$ This product is issued around 5 AM and 5 PM each day and weather conditions may change between issuances.
