All coastal watches and warnings were discontinued on Wednesday, but flooding is likely through Friday over parts of Texas, Louisiana, Mississippi, Georgia and the Florida panhandle, the hurricane center said.Some communities in Louisiana and Mississippi were distributing sand bags to residents and cleared debris from drainage systems ahead of the storm.“The main threat from Arthur is going to be a prolonged, multiday, heavy rainfall event that could produce dangerous to life-threatening flash flooding,” National Hurricane Center director Michael Brennan said.“A significant flood risk exists each day this week, shifting slowly eastward from Texas into Wednesday to Louisiana, Mississippi, Alabama and Georgia during the second half of the week,” said Dan DePodwin, AccuWeather Vice President of Forecast Operations.Arthur has expected rainfall totals of 5 to 10 inches (13 to 25 centimeters), with isolated higher totals near 20 inches (50 centimeters).“A High Risk for Excessive Rainfall has been issued for portions of the Central Gulf Coast today. High Risks are not issued lightly & indicate the potential for both widespread & life-threatening flash flooding,” stated the National Weather Service weather prediction center. “NEVER walk or drive into flood waters. Turn around, don’t drown!”Swells generated by the storm are expected to cause life-threatening surf and rip-current conditions along the northwestern Gulf Coast over the next couple of days, said forecasters, with tornados possible through Thursday.
