Extreme Weather Grips U.S.: Tropical Storm, Heat Dome, and Toxic Air
The United States is experiencing a range of extreme weather conditions, including severe thunderstorms, a heat dome, and lingering wildfire smoke. The National Weather Service has issued warnings for flash flooding across the Midwest, Northeast, and Mid-Atlantic regions on July 20 and 21 due to potent thunderstorms. Meanwhile, a tropical depression in the Gulf of Mexico is expected to intensify into Tropical Storm Bertha, bringing heavy rain and strong winds to areas from Texas to the Florida Panhandle. Additionally, a heat wave is affecting the central U.S., with heat indices reaching up to 116°F (46.7°C) in some areas. Toxic smoke from Canadian wildfires continues to impact air quality in the Great Lakes and Midwest regions, with alerts issued for sensitive groups. These conditions follow recent flash flooding that caused fatalities in Texas, Arizona, and Utah.
