URGENT P.D.S. INFORMATION

This section contains vital information when a significant or "major" severe weather event is forecast for any part of our coverage region. This includes major severe thunderstorm and tornado outbreaks. Please note: this information will be provided only as necessary!

PDS PRODUCT TYPE ISSUE TIME (UTC) DESCRIPTION OF PRODUCT AVAILABILITY
SPECIAL STATEMENT FOR SEVERE THUNDERSTORMS 0000 UTC To provide critical information concerning Derecho events.
SPECIAL STATEMENT FOR TORNADOES 0000 UTC To provide critical information concerning tornado events.

The above flashing light is our "Severe Weather Indicator". This light will change color when a specific type of outbreak is forecast. This is described below:
Flashing Green Light This indicates no significant severe weather event is expected.
Flashing Yellow Light This indicates a possible significant severe weather event within 24 hours.
Flashing Blue Light This indicates a Derecho event is expected.
Flashing Red Light This indicates a significant tornado event is expected.

Please note: There maybe occasions when a mix of tornado and severe thunderstorm events are forecast. When this is the case, we will attempt to indicate which event type is most likely to occur, then display the indicator light accordingly. You need to remember that this can be very difficult to determine at times, but we will do our best.
