KSZ055-152115-
Osage-
327 PM CDT Mon Mar 15 2021

...SIGNIFICANT WEATHER ADVISORY FOR CENTRAL OSAGE COUNTY UNTIL 415 PM
CDT...

At 326 PM CDT, Doppler Radar was tracking a storm that could produce
funnel clouds. These clouds normally lower a few hundred feet
downward from the parent cloud, rotate or spin like a top, and last
only a few minutes. Current conditions make it unlikely these funnel
clouds will lower to the ground or do any damage. Persons should
remain alert and move to a safe place if a funnel cloud approaches.

Locations impacted include...
Lyndon and Pomona Lake.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

This storm may intensify, so be certain to monitor local radio
stations and available television stations for additional information
and possible warnings from the National Weather Service.
