The remnants of what was tropical storm Dolly, now a tropical wave, are expected to begin affecting Puerto Rico from Sunday afternoon, bringing increased shower activity, wind gusts, and deteriorating marine and coastal conditions. Meteorologist Mariangelis Marrero of the National Weather Service (NWS) told El Nuevo Día the system would first reach the Virgin Islands early Sunday, with effects on Puerto Rico becoming clearer by about 1:00 PM. The NWS anticipates general rainfall accumulations of one to three inches, with some areas—particularly in the west during typical afternoon shower development—possibly receiving higher amounts.
Rain activity could persist through Monday. Marrero clarified that Saturday’s early-morning showers were unrelated to Dolly, instead linked to a weak tropical wave passing mostly south of Puerto Rico, with some moisture reaching eastern, southern, and interior areas. A drier air mass was expected the rest of Saturday, with a heat advisory in effect for coastal and urban areas and an elevated fire danger notice.
Given the current state of several of the island’s reservoirs, Marrero said some showers could reach the Carraízo and La Plata basins, though it remains uncertain whether the heaviest rainfall will fall precisely over those needed areas.
