Abstract: A system for providing real-time site specific weather information includes a plurality of remote sensing units, each of which incorporates an electronic messaging system for delivering electronic messages indicative of ground level meteorological observations, and a server system communicating with the remote sensing units to receive the electronic messages. The server system includes a database for storing information pertaining to the remote sensing units and instructions for routing the received electronic messages. At least one remote system is configured to receive non-ground level meteorological data indicative of a weather phenomenon and to associate the electronic messages with the non-ground level meteorological data for graphical display together with a graphical view of the geographic area affected by the weather phenomenon and the ground level meteorological observations. A method for providing real-time site specific weather information is also disclosed.

Abstract: An event notification system in accordance with the present invention includes a computer system configured to receive data indicative of an event to be warned for and to process the data to define a boundary for an area affected by the event. A distribution site communicates with the computer system to distribute information indicative of the boundary of the area affected by the event to a plurality of devices remote from the distribution site and each other. The plurality of remote devices communicate with the distribution site to receive information indicative of the boundary of the area affected by the event and each is configured to determine if it is affected by the event and to respond accordingly. A method of remotely activating a warning device in response to an event notification is also disclosed.
