There is a low chance of localized urban and small streams flooding. .Excessive Heat...This level of heat affects most individuals sensitive to heat, especially those without effective cooling and/or adequate hydration. Those extremely sensitive to heat face the highest risk. Some health systems and heat-sensitive industries could be affected. These conditions are most likely across most lower elevations and urban areas. .Wind...Breezy conditions (18-22 kts | 21-25 mph), particularly across coastal areas of southern Puerto Rico and Vieques. Unsecured items could blow around. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday Excessive heat concerns are expected to persist throughout the forecast period. A series of tropical waves, anticipated to arrive later this week and continue into early next week, will potentially increase the potential for showers and thunderstorms, thereby raising the risk of localized flooding. Breezy to locally windy conditions may offer limited heat relief but will likely elevate marine hazards starting Thursday. A moderate rip current risk will return and expand through most surf zones as the wind increases by the end of the workweek into the weekend. .SPOTTER INFORMATION STATEMENT...
