Weather conditions in Puerto Rico will improve gradually on Friday due to the arrival of drier air, according to the National Weather Service in San Juan. However, daytime heating and local effects will still favor the development of scattered showers and isolated thunderstorms in the afternoon, mainly in the interior, west, and southwest sectors. The risk of heat will remain limited, but warm temperatures will continue.
Authorities recommend staying hydrated and seeking shade during peak heat hours. The improvement on Friday will be temporary, as a low-pressure system in the upper atmosphere will increase instability and the potential for thunderstorms on Saturday, making the weekend outlook more rainy. Winds will blow from the east in the morning and shift to east-northeast in the afternoon, bringing somewhat cooler and windier conditions to the island.
