Storm brings drenching rain to Gulf Coast
NEW ORLEANS — A lopsided Tropical Storm Cristobal came ashore Sunday in Louisiana and ginned up dangerous weather much farther east, sending waves crashing over Mississippi beaches, swamping parts of an Alabama island town and spawning a tornado in Florida.
Cristobal made an afternoon landfall between the mouth of the Mississippi River and the since-evacuated barrier island resort community of Grand Isle, the storm packing 50 mph winds.
The storm had begun weakening as it moved inland late Sunday night though heavy rainfall and a storm surge were continuing along the Gulf Coast, posing a threat across a wide area into the Florida Panhandle.
At 10 p.m. CDT, the storm was centered about 20 miles north-northwest of New Orleans and it packed sustained 45-mph winds. With its drenching rains, Cristobal was expected to keep inundating the northern Gulf Coast well into Monday.
In New Orleans, the question was how much rain would fall and whether there would be enough breaks in the bands of heavy weather for the beleaguered pumping system to meet its latest test of keeping streets free of floodwaters.
President Donald Trump agreed to issue an emergency declaration for Louisiana, officials said.
Coastal Mississippi news outlets reported stalled cars and trucks as floodwaters inundated beaches and crashed over highways. On the City of Biloxi Facebook page, officials said emergency workers helped dozens of motorists through flood waters, mostly on U.S. 90 running along the coast.
In Alabama, the bridge linking the mainland to Dauphin Island was closed much of Sunday. Police and state transportation department vehicles led convoys of motorists to and from the island when breaks in the weather permitted.
Forecasters said up to 12 inches of rain could fall in some areas. The weather service warned that the rain would contribute to rivers flooding on the central Gulf Coast and up into the Mississippi Valley.
Cristobal was expected to be downgraded to a depression by Monday afternoon but had the potential to be a rainmaker for days. Its forecast path takes it through Louisiana on Sunday night and Monday, continuing into Arkansas and Missouri by Tuesday and heading up through Illinois and Wisconsin to the Great Lakes.
Though Cristobal was well below hurricane strength at landfall, forecasters warned that the storm would affect a wide area stretching roughly 180 miles along the Gulf Coast.
In Florida, a tornado — the second in two days in the state as the storm approached — uprooted trees and downed power lines Sunday afternoon south of Lake City near Interstate 75, the weather service and authorities said. There were no reports of injuries.
The storm also forced a waterlogged stretch of Interstate 10 in north Florida to close for a time Sunday.
