📅 Sep 17, 2026. Moisture trailing a departing tropical wave will keep the atmosphere unsettled today. Expect a transition from morning showers and thunderstorms over the eastern islands and eastern Puerto Rico to more afternoon convection downwind of the islands and mountains, including northwestern Puerto Rico. The rainfall will be beneficial for areas affected by dry conditions and may help reservoir levels, but periods of heavy rain and thunderstorms still warrant caution. 17 de septiembre de 2026.

La lluvia será beneficiosa para las zonas secas y los embalses, pero se recomienda precaución durante aguaceros fuertes y tormentas.
