Personalized weather alerts in the palm of your hand!
StormWatch+ is a personalized service that sends alerts to smartphone users whenever severe
weather threatens their specific location. Combining storm-based warnings issued by the
National Weather Service (referred to as polygons) and a user's precise location, alerts are sent
only if the user's registered location(s) is directly threatened.

In 2007, the National Weather Service began issuing Tornado, Severe Thunderstorm, and Flash
Flood Warnings as polygons (see images to the right), alerting only the areas in the path of the storm,
rather than entire counties. However, for various reasons, and in almost all cases, outdoor warning
sirens still sound over the entire county even if the storm is affecting only a small portion of that
county. This can create an overwarned public and increases the perceived warning false alarm rate,
thereby reducing the siren's effectiveness and, consequently, the public's response. In addition, NOAA
Weather Radios also alert on a COUNTY basis and are therefore not as precise as the warnings they
are alerting on.
At a "Weather-Ready Nation" conference in Oklahoma City, panelists stated that cell phones and
geotargeted alert information are the most important warning dissemination technology available.
In addition, a finding of the NWS Service Assessment of the Joplin, MO Tornado indicated that
"many current warning dissemination systems are not fully compatible with specific warning information
provided by storm-based, warning polygons." Officials at the highest level are giving credence
to the use of geo-targeted alerts and warning systems that can provide very specific information.
What is StormWatch+?
StormWatch+ keeps you from becoming "siren-weary" and "overwarned" by only alerting you if you
are directly in the path of the storm. If sirens or your NOAA Weather Radio sound an alarm, but
a StormWatch+ alert is not received, you are NOT in the NWS-warned area. For less than the cost of a
meal at your local fast casual restaurant, you can have peace of mind in the path of the storm!
