San Juan on Saturday set a 38-year rainfall record for the date with double the amount of precipitation established in the old record.
On Nov 30, authorities registered 8.53 centimeters (3.36 inches) of rain at the Luis Muñoz Marin International Airport in the capital, the Puerto Rico office of the U.S. National Weather Service said Sunday.
This is the greatest quantity of rain registered on the date of Nov. 30 since 1975, when 4.24 cm (1.67 inches) fell, the National Weather Service said.
Although the day started out sunny in San Juan, the weather service warned that downpours could occur throughout the day in eastern Puerto Rico and on the nearby islands of Vieques and Culebra.
“Unstable atmospheric conditions combined with moist southeasterly flow will continue to bring periods of moderate to locally heavy showers and a few thunderstorms over the local islands today,” the National Weather Service said in a special bulletin.
“Due to already saturated soils ... any additional rainfall will likely result in sharp rises in small streams and creeks as well as urban flooding in portions of Puerto Rico ... Culebra and Vieques,” the service said.
In St. Thomas and the U.S. Virgin Islands, a rainfall record was also set on Saturday for Nov. 30, breaking the old record set in 1994, the weather service said.
