Severe Thunderstorms, High Winds in the Forecast; Could Bring Possible Power Outages

Posted at 9:30 a.m.

The National Weather Service (NWS) and county emergency management officials are monitoring the progress of a powerful cold front that is forecast to affect our area this afternoon. With temperatures rising to near 80 degrees there will be an unusual amount of heat energy available for this time of the year to fuel thunderstorms as the cold front passes. The primary threat will be high winds and related power outages. In addition, isolated thunderstorm cells could also bring us hail and wind gusts to 40 mph or greater.

NWS reports scattered severe thunderstorms with damaging winds and large hail are possible this afternoon and evening. The most likely time for severe thunderstorms is between 2 p.m. and 9 p.m.

It’s Not Too Late to Winterize Your Vehicle

Posted at 2 p.m.

Don’t hit the road without a jack or until your car is ready for winter weather. There are maintenance checks to keep you safe, your vehicle warm and your engine running — as well as specific emergency items to store in your car during the winter.

Check or have a mechanic check items, such as:

  • Antifreeze levels — ensure they are sufficient to avoid freezing.
  • Battery and ignition system — should be in top condition and battery terminals should be clean.
  • Exhaust system — check for leaks and crimped pipes and repair or replace as necessary. Carbon monoxide is deadly and usually gives no warning.
  • Heater and defroster — ensure they work properly.
  • Lights and flashing hazard lights — check for serviceability.
  • Windshield wiper equipment — repair any problems and maintain proper washer fluid level.
  • Install good winter tires — Make sure the tires have adequate tread. All-weather radials are usually adequate for most winter conditions.

You’ll also want to add winter items to the emergency kits in all your vehicles:

  • A shovel.
  • Windshield scraper and small broom.
  • Water.
  • Snack food.
  • Extra hats, socks and mittens.
  • Necessary medications.
  • Blanket(s).
  • Tow chain or rope.
  • Road salt and sand.

Learn more on how to make an emergency kit for your vehicle(s) in this short video from the county’s Office of Emergency Management.
