Tropical Storm Theta became the 29th storm of the exceptionally active and record-breaking 2020 Atlantic hurricane season Monday night. No year on record has ever seen so many named storms, and officials are tracking two systems that could become named storms in the coming days. Meanwhile, Tropical Storm Eta, which already caused widespread devastation across Central America, dumped more than 13 inches of rain across South Florida and inundated coastlines with storm surge, leaving thousands without electricity. Climate change is increasing extreme precipitation and storm surge.
