The National Weather Service and You

Without a doubt, the most effective way to learn about impending bad weather is the National Weather Service (NWS). The NWS, located in Boulder, provides weather, water, and climate data, forecasts and warnings for the protection of life.

This NWS center is monitored 24-hours-a-day, seven-days-a-week providing up-to-the-minute tracking of weather within the area. The Longmont Office of Emergency Management highly recommends residents familiarize themselves with these resources and sign up for the notifications they provide. They are clearly the most effective way to receive information about the weather: 

HOW TO GET WEATHER ALERTS: The Longmont Office of Emergency Management encourages residents to use the following National Weather Service (NWS) based notification systems for Boulder County because the emergency sirens are no longer in use:

  • Facebook
  • Twitter
  • Website
  • Weather radio - Information transmitted from a weather radio does not require internet service. This information is distributed directly from the National Weather Service Boulder County. Weather radios can be purchased at most hardware and retail stores that sell electronics.

Should you have further questions, please contact the Office of Emergency Management at (303)774-3793.



The notification systems listed below are NOT generally used for impending weather, but are important notification systems for our residents to sign up for:
  • Please take a minute to sign up for the Reverse 9-1-1 for mobile devices system. This is a notification tool that allows the city to contact you via email as well on other mobile devices based on the type of emergency. For additional information, details and sign-up information for mobile devices, please visit our web page.
  • The city also has an email based subscription called e-notification. Although this system is not intended for emergency notification, city personnel can use it to send email messages directly to subscribers with late-breaking updates on issues such as West Nile virus, traffic street closures, city council news and several other categories. For more information on e-alert notifications.

    For more information about emergency preparedness in Longmont, please call the City of Longmont, Office of Emergency Management at (303) 774-3793 or email.
