The National Weather Service in San Juan confirmed on Tuesday that Puerto Rico will continue to experience an unstable weather pattern favoring heavy rain and thunderstorms, particularly in eastern, interior, and western municipalities. [^1]

The National Weather Service (NWS) in Puerto Rico forecast on 2026-07-14 that additional showers would cross eastern Puerto Rico during the morning, with stronger showers and thunderstorms in the afternoon due to lingering tropical moisture and local effects. [^2]

The NWS reported that during the night of 2026-07-13, periods of heavy rain and wind gusts moved from Caribbean waters toward southeast Puerto Rico, leaving estimated accumulations of 2 to 4 inches of rain. [^3]

The NWS warned on 2026-07-14 that the afternoon shower and thunderstorm activity would maintain a risk of flooding between limited and elevated, along with risks of strong wind gusts near the most intense showers and lightning danger. [^4]

USGS river gauges indicated on 2026-07-14 that some rivers in Puerto Rico reached levels requiring attention or minor to moderate flood levels, including the Guayanés river in Yabucoa, where a Flood Advisory remained in effect until 8:00 a.m. [^5]

Rain bands over El Yunque are expected to move toward the San Juan metropolitan area, potentially causing moderate to heavy rainfall with a 50 percent probability of accumulating between three-quarters of an inch and one inch. [^6]
