---------------------------------------------------------------------
Watches/warnings in effect for southern Alberta...

Tornado Watch for:
      Red Deer - Ponoka - Innisfail - Stettler.

      Funnel clouds reported near red Deer this evening.

      Conditions are favourable for the development of funnel clouds
      and tornadoes. These types of tornadoes form out of weak
      thunderstorms and are usually not as destructive as their
      severe thunderstorm cousin. They are difficult to track with
      Doppler radar and can appear without warning. They normally
      move slowly and can last for many minutes. They often appear as
      a giant column of dust from the ground to the bottom of the
      thunderstorm. Their destructive power is usually felt over a
      very small area.

      Treat all funnel clouds and tornadoes seriously and avoid when
      possible. Should one develop nearby take shelter underground or
      in a reinforced structure like a bathroom or interior closet.
      If you are in your vehicle try to move away from the tornado at
      right angles.

      Environment Canada continues to monitor the situation closely.
      Please continue to monitor your local media or weatheradio for
      further updates.

      Should you spot a funnel cloud or tornado...and only if it is
      safe to do so...you can call 1-800-239-0484 to report your
      sighting. Please note this phone number is for reporting severe
