Unusual Severe Weather Threat in Northwest

Large hail (1") and damaging thunderstorm winds (58 mph or more) are possible with 15% being the significant threshold.

I don't recall ever seeing 30% probabilities in this area before. These are for the combined large hail and damaging wind threat.

Some preliminary precautions:

  • Bring cars indoors
  • Bring in trampolines and lawn furniture
  • Remember that lightning is also a hazard in severe thunderstorms.
