Sheriff shares severe weather notification plan

The National Weather Service and other state and local agencies will host Severe Weather Awareness Week activities this week including a tornado drill on Thursday, April 19. Chisago County will participate in and activate the sirens at 1:45 p.m. and 6:55 p.m.

The Sheriff’s Office notes that due to the unpredictable nature of severe weather, it is the Sheriff’s Office policy that if any portion of Chisago County is included in a warning, weather sirens will be sounded for the entire county.


A warning indicates that people in the approaching storm path should seek shelter immediately and monitor storm information if possible. Warnings are disseminated over NOAA weather radio, commercial radio, television stations and news wires.

Warnings will be issued when severe hail (quarter size or larger), damaging winds (at least 58 mph) or a tornado appears imminent.

The Sheriff’s Office will not issue an “all clear” after the storm has passed.


If development of severe thunderstorms is imminent, or likely to occur in the next several hours a Severe Thunderstorm or Tornado Watch is issued by the National Weather Service. A watch indicates that the atmosphere conditions have become favorable for the development of severe storms or tornadoes.

The Chisago County Sheriff’s Office says it is the public’s responsibility to monitor available media sources to determine appropriate steps to take to ensure personal safety. They ask that people develop and practice a severe weather plan with their famiies to ensure everyone’s safety during the upcoming storm season.
