Jacksonville, on Florida’s northeast Atlantic coast, receives around 1,320 mm (about 52 inches) of rain a year, with a clear summer wet season driven by daily sea-breeze thunderstorms and direct exposure to Atlantic hurricanes from June through November. The St. Johns River, which runs unusually north through the city, has a history of both hurricane-driven storm surge and heavy-rain flooding, a combined risk underscored by Hurricane Irma in 2017 which caused record river flooding downtown. Because the city faces both routine summer thunderstorms and the more serious tropical threat, radar tracking matters throughout the entire wet season, not just during named storms. NWS Doppler radar KJAX (Jacksonville, FL) covers the region.
