MINNEAPOLIS (AP) - Minneapolis Public Schools are preparing for a scorcher on the first day of class.

Minneapolis students go back to school Monday. Faced with an excessive heat warning that's in effect through Tuesday, the district has already started to cool buildings. Schools will provide extra water and have canceled all outdoor after-school athletics practices for Monday.

District spokeswoman Rachel Hicks says they ask that prepare students for the excessive heat by dressing them in light-colored, light-weight, loose fitting clothing and ensure that they have plenty of fluids to stay hydrated.

Minneapolis has 18 public school buildings that do not have any air conditioning. Eleven buildings have partial air conditioning while 36 have full AC.

St. Paul Public Schools don't resume classes until right after Labor Day.
