Laura is predicted to hit the U.S. Gulf Coast as a Category 2 hurricane later this week — bringing heavy rain to some of the same areas that are being drenched by Marco.
One storm is currently forecast to hit near the Texas-Louisiana border; the other could reach the Florida Panhandle. Two hurricanes hitting the Gulf at once would be unprecedented, experts say.
"We've never forecast up to 25 storms," says a NOAA expert. The expected spate of storms in 2020 could force meteorologists to resort to using the Greek alphabet to name storms later this year.
The National Hurricane Center says the storm's eye came ashore near Ocean Isle Beach. It's expected to linger in North Carolina, traveling inland before swirling up the Mid-Atlantic coast.
Heavy rainfall and life-threatening flash flooding continue after Tropical Storm Hanna hit South Texas. Meanwhile, Hurricane Douglas is closing in on the islands of Hawaii.
Federal forecasters expect 3 to 6 major hurricanes during the 2020 hurricane season, which runs from June 1 to November 1. Rising seas and a warmer climate make storms of all sizes more damaging.
