Information:

Monitor the latest forecasts for updates on this situation.

Persons are urged to stay indoors until conditions improve. If you
must go outside, dress in layers. Several layers of clothes will
keep you warmer than a single heavy coat. Cover exposed skin to
reduce your risk of frostbite or hypothermia. Gloves, a scarf, and a
hat will keep you from losing your body heat.

Persons should delay all travel if possible. If travel is absolutely
necessary, drive with extreme caution and be prepared for sudden
changes in visibility. Leave plenty of room between you and the
motorist ahead of you, and allow extra time to reach your
destination. Avoid sudden braking or acceleration, and be especially
cautious on hills or when making turns. Make sure your car is
winterized and in good working order.
