           from the La Junta automated observing system.

  IMPACT...Hail damage to vehicles is expected. Expect considerable

           roofs, and outbuildings.

* Locations impacted include...

  Sheridan Lake, Haswell, Neeoshe Reservoir, McClave, Chivington,

  Reservoir, Arlington and Queens Reservoir.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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