Understanding High Wind Alerts: A Guide to National Weather Service Warnings
High winds can pose significant risks, from property damage to personal injury. The National Weather Service (NWS) issues specific alerts to inform the public about impending high wind events. Understanding these alerts is crucial for timely and appropriate responses.
What Are High Wind Alerts?
High wind alerts are notifications issued by the NWS to warn the public about expected or occurring strong winds that could be hazardous. These alerts are categorized into three main types:
- High Wind Watch: Indicates that high wind conditions are possible but not yet certain.
- High Wind Warning: Signifies that high wind conditions are expected or occurring.
- Wind Advisory: Alerts to less severe but still significant wind conditions.
High Wind Watch
A High Wind Watch is issued when sustained winds of 40 mph or higher and/or gusts of 58 mph or higher are possible. This alert serves as a heads-up, allowing individuals to prepare for potential high wind events. It's important to secure loose outdoor items and adjust plans as necessary to avoid being caught outside during these conditions. (weather.gov)
High Wind Warning
A High Wind Warning is issued when sustained winds of 40 mph or higher and/or gusts of 58 mph or higher are expected or occurring. This alert indicates imminent danger and requires immediate action. Individuals should seek shelter, secure outdoor items, and exercise caution if driving, as high winds can make driving hazardous. (weather.gov)
Wind Advisory
A Wind Advisory is issued when sustained winds of 30-39 mph and/or gusts of 45-57 mph are expected. While not as severe as a High Wind Warning, these conditions can still cause minor damage and pose risks, especially to high-profile vehicles. It's advisable to secure outdoor items and exercise caution when driving. (weather.gov)
Understanding the Criteria
The NWS defines high winds based on specific criteria:
- Sustained Winds: Continuous wind speeds over a period of time.
- Wind Gusts: Sudden, brief increases in wind speed.
For valley locations, a High Wind Warning is issued when sustained winds reach 40 mph or higher, or gusts reach 58 mph or higher. In mountain locations, the thresholds are sustained winds of 50 mph or higher, or gusts of 75 mph or higher. (weather.gov)
