All Houston ISD after-school activities are canceled for Feb. 3 due to inclement weather, according to a statement from the HISD Press Office.

The district's announcement comes after the National Weather Service for the Houston/Galveston area said an arctic front passed through the area the evening of Feb. 2. A winter weather advisory is in place for Harris County with hazards such as light freezing rain and sleet starting in most of the county around 2 p.m.

Ice accumulations of up to one-tenth of an inch are possible, according to the NWS. Slippery conditions may develop on some roads with the greatest risks on elevated roads, bridges and overpasses. The winter weather advisory will continue into the night, during which temperatures are expected to dip into the mid 20s.

HISD officials said they are monitoring the weather situation, and updates on district activities for Feb. 4 are expected to be released later Feb. 3.
