Two South Mississippi cities are moving Halloween events and trick-or-treating to Friday night because of expected bad weather.
Bay St. Louis and Waveland announced on their websites Thursday they are rescheduling Halloween activities.
Waveland's annual Halloween Bash will be 5:30 to 8 p.m. Friday, and Bay St. Louis is asking residents to trick or treat Friday.
The National Weather Service in Slidell forecasts a cold front will bring widespread showers and thunderstorms Saturday and Sunday. Strong to severe storms are possible Saturday afternoon and night.

The NWS also warns flash-flood warnings are possible, especially because the ground cannot hold as much water after last week's storm system.
Total rainfall is expected to be between 1 and 4 inches, but in some areas it could be much higher, the weather service said.
The main threats from strong storms would be damaging winds and isolated tornadoes.
Friday is forecast to be partly cloudy with lows in the mid-60s.
Saturday has a slight chance of rain early, then 70 percent chance in the afternoon and night. Sunday's chance of rain starts at 60 percent and falls to 40 percent at night. Highs should be in the mid-70s both days with lows in the mid- to low 60s. Monday's chance of rain is 20 percent.
An indoor trick-or-treating event is planned at Edgewater Mall. Merchants will hand out candy from 5:30 to 7:30 p.m.
