The worst of the weather is expected Saturday afternoon and should end between 6 p.m. and midnight, the National Weather Service said. Waveland’s annual St. Patrick’s Day Parade will now roll at 2 p.m.

Two St. Patrick’s Day parades have been rescheduled for Sunday due to severe thunderstorms forecast to surge across the Mississippi Coast this weekend. Forecasters said the storms could be severe, with wind gusts over 60 mph and hail larger than a quarter.
