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 all lower elevations and urban areas. .Wind...Breezy conditions (18-22 kts | 21-25 mph), particularly across coastal areas of northern and southern Puerto Rico, Vieques, and Culebra. Unsecured items could blow around. .Marine Conditions...Small craft should exercise caution, particularly across the Atlantic and Caribbean waters, including the Mona Passage. .Rip Currents...Life-threatening rip currents are possible in the surf zone, particularly across northern, eastern, and southeastern Puerto Rico, including Vieques, and Culebra. Isolated stronger rip currents may occur elsewhere, especially near piers, jetties, and channels. .DAYS TWO THROUGH SEVEN...Saturday through Thursday A limited to elevated excessive heat threat will likely persist over the period. Breezy to locally windy conditions, while offering little relief from the heat, will maintain a moderate risk current risk, along with choppy, wind-driven seas through the weekend, and again from Tuesday onward. Although isolated afternoon thunderstorms may develop, particularly early next week, they are not expected to produce significant flooding impacts. Moderate to high concentrations of Saharan Dust will also persist through at least Sunday, contributing to hazy skies and reduced air quality. A tropical wave is expected to increase shower and thunderstorm activity by midweek. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed. $$
