BULLETIN - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Warning
National Weather Service Pueblo CO
444 PM MDT Sun May 2 2021

The National Weather Service in Pueblo has issued a

* Severe Thunderstorm Warning for...
  Prowers County in southeastern Colorado...
  Southeastern Kiowa County in southeastern Colorado...
  Southeastern Bent County in southeastern Colorado...

* Until 545 PM MDT.

* At 440 PM MDT, the leading edge of a line of severe wind gusts 
  associated with thunderstorm activity was located along a line 
  extending from near Sheridan Lake to near Two Buttes Reservoir, 
  moving east at 45 mph. Severe winds will extend far away from 
  thunderstorm activity.

  HAZARD...70 mph wind gusts and quarter size hail. Brief, weak 
           circulations could accompany the leading edge of this 
           activity, producing locally higher wind gusts. Also, 
           blowing dust reducing visibilities to one-quarter mile is 
           expected in some locations, producing very hazardous 
           travel.

  SOURCE...The Lamar automated observing system reported a 60 mph 
           wind gust.

  IMPACT...Hail damage to vehicles is expected. Expect considerable 
           tree damage. Wind damage is also likely to mobile homes, 
           roofs, and outbuildings.

* Locations impacted include...
  Holly, Granada, Hartman and Bristol. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

For your protection move to an interior room on the lowest floor of a
building.

Wind damage with these storms will occur before any rain or
lightning. Do not wait for the sound of thunder before taking cover.
SEEK SHELTER IMMEDIATELY inside a sturdy structure and stay away from
windows.

Intense thunderstorm lines can produce brief tornadoes and widespread
significant wind damage. Although a tornado is not immediately
likely, it is best to move to an interior room on the lowest floor of
a building. These storms may cause serious injury and significant
property damage.

Prepare for blowing dust significantly reducing visibilities.
