A 2 hour delay
On a delay morning every school starts 2 hours late.
“If schools are delayed due to weather, the decision also will be made by 5:30am. The decision to have a TWO HOUR delayed opening is based upon the available information that travel and weather conditions are expected to sufficiently improve to open schools.”
