It's not the weather, but the water cancelling school in Madison, South Dakota, on Thursday.
The roof over a well collapsed Wednesday night, contaminating water in the city. It happened just as workers were leaving for the day.
Crews spent the night pumping out all the water from the well, so they can clean out their system and start putting water back into the water towers.
Mayor Roy Lindsay says residents might have water for showering and other uses by late Thursday, but clean, drinkable water likely won't be available until sometime Friday. People in Madison are urged to boil any water from the tap until they're told otherwise.
Lindsay says two stores are bringing in semitrailer-loads of bottled water for residents, and the city also is bringing in two semi-loads. He says that water will go first to a hospital and two nursing homes, and then to residents.
Madison Central and St. Thomas schools are canceled Thursday because of the contamination.
There’s no word yet on when water service will be back to normal.
