Non-Thunderstorm Wind Hazards

RISK LEVEL
HAZARD DESCRIPTION
Low
  • Windy conditions expected with sustained winds of 25 to 30 mph expected for at least an hour, or gusts not associated with thunderstorms of up to 45 mph.
Moderate
  • Wind advisory criteria likely to be met, with sustained winds of 31 to 39 mph expected for at least an hour, or gusts not associated with thunderstorms of 46 to 57 mph.
High
  • High wind warning criteria likely to be met, with sustained winds greater than or equal to 40 mph expected for at least an hour, or gusts not associated with thunderstorms of 58 mph or greater.

General Information

Strong winds not associated with thunderstorms are often referred to as gradient winds. They are usually the result of tight pressure gradients between strong areas of low pressure and high pressure. These strong winds can be just as strong as thunderstorm wind gusts, but cover a much larger area, and can result in widespread damage.

Winds associated with tropical systems are also covered in this category.

High Wind Safety Tips:
  • Strong gusty winds will make travel difficult, especially if you are driving a high profile vehicle. Motorists should use extreme caution. Persons planning to drive should consider delaying travel until the high wind threat diminishes.
  • People at home should secure any loose outdoor items shuch as garbage cans and lawn furniture.
  • Stay alert for the possibility of falling tree limbs and downed power lines.

This Outlook is an Experimental Product for Planning purposes Only!!!

The local tornado hazard graphics are valid for roughly a 24 hour period from the time of issuance (between 4 AM and 6 AM) until 8 AM the following morning. The highest expected risk possible for the duration of the graphic will be depicted. Only one of the listed criteria needs to be met fo inclusion in a higher risk category

Updates will be posted for significant forecast changes and as time permits. As the weather threat increases throughout the day, or becomes imminent, tornado watches and/or warnings will be issued.

The outlook graphics are an effort to improve the interpretation of our outlooks and statements. This product is provided for emergency managers, law enforcement, schools, local media, businesses, and the public. Use the graphical hazardous weather outlook to factor the threat of hazardous weather into your daily plans.
