e-mail, or log into espotter to access informational or activation messages.)
2. EMA Vanderbrugh County Activation- Personnel at the EMA will activate a weather net if amateurs in
the area have not already done so. If EMA personnel are running a local weather net they will gladly give Net
Control to you to. To gain the privileges of operating net control simply let the EMA operator know that you're
willing and prepared to take net control and it will be turned over to you.
3. Local Storm Spotter Activation- Area spotter sees or anticipates severe weather and is prepared to
activate a weather net. Contact the Vanderburgh EMA to notify that a weather net has been activated. Call the VEMA at 435-6020
Once a net has been activated there are 2 levels of activation which are: a STANDBY or Watch Net, and
an EMERGENCY NET. Both nets could be called SKYWARN Nets depending on if the National Weather Service activates SKYWARN spotters
under the SKYWARN program.
