🌊 A strengthening nor’easter is bringing heavy rain, strong winds, dangerous surf, and coastal flooding along the U.S. East Coast this weekend! Coastal flooding has already affected portions of Virginia and North Carolina, with ocean overwash closing a miles-long stretch of road on the Outer Banks.

🌡️Humid heat can be dangerous to human health. High humidity makes it harder for sweat to evaporate, reducing the body’s ability to cool itself and increasing the risk of heat-related illness. Learn more with #ClimateCentral: www.climatecentral.org/climate-matt...

🌧️ As #HurricaneLowell approached Hawaii and made its closest pass on Labor Day Monday, rainfall totals on Kauai exceeded 16–19 inches. 🚨The storm washed out roads, triggered flash flood warnings, and prompted the first-ever tornado watch issued for Hawaii!

🌀 #HurricaneLowell brought torrential rainfall to Hawaii — and climate change helped make its Pacific environment unusually warm. Human-caused climate change made the unusually warm sea surface temperatures along Lowell’s path up to 60 times more likely.
