Understanding Weather Forecast Refresh Rates During Severe Weather

During severe weather events, timely and accurate information is crucial for safety. Understanding how often weather forecasts and radar images update can help you make informed decisions.

How Often Do Weather Forecasts Update?

Weather forecasts are updated at varying intervals depending on the source and the type of forecast:

• Short-Term Forecasts: These provide detailed information for the next few hours to a day and are typically updated every hour.

• Long-Term Forecasts: Covering periods from a day to several days ahead, these forecasts are usually updated four times daily at 00:00, 06:00, 12:00, and 18:00 UTC.

How Often Do Radar Images Update?

Radar images, which show real-time weather conditions, are updated more frequently:

• NEXRAD Radar: Operated by the National Weather Service, NEXRAD radars complete a full volume scan approximately every 4.5 minutes during severe weather modes. This means radar images are refreshed every few minutes, providing near-real-time data. (climeradar.com)
