NWS Chicago on Facebook and Twitter

 As the National Weather service continues to seek new ways to reach its partners and the public, the Chicago National Weather Service has expanded its presence within the social media world. We are now on Twitter and can be found with our Twitter handle, @NWSChicago, and also continue to maintain a strong presence on Facebook, US National Weather Service Chicago Illinois.  



We look forward to both of these social media outlets as supplements to our many ways of providing weather/water information to the public and our partners. Our presence on Twitter will aim at helping to disseminate life saving information; increase the public's understanding of weather, water, and climate; and heighten awareness through education and encouragement of public response/action.

The frequency of updates posted to this feed may vary and is not guaranteed.


Followers should not rely on this service as the primary means of receiving alerts/warnings of hazardous weather. NWS alerts/warnings are available on NOAA Weather Radio and our official website: http://www.weather.gov/chicago.

Responses to timeline posts are made on a time-available basis and may be extremely limited during periods of severe weather.
