The state's 911 office will send alerts to phones, pagers, e-mail or fax machines. Residents will receive a recorded or electronic message giving them details of the situation.
Connecticut State Police spokesman, Lieutenant Paul Vance, says the alerts will only be sent in life-threatening situations.
"This, simply stated, is an informational highway, it's a communication system that will certainly not create panic. It's designed to inform the public in the event of an oncoming emergency. A hurricane is coming, a tornado might be expected, wild fires," Vance said.
The governor's office estimates the project costing about $1.4 million the first year. It would cost about half that amount in the following years.
The program is funded through fees paid by wireless phone customers. The money is then sent to the state's Office of Statewide Emergency Telecommunications, and added to the 911 fund.
The system is already working in some Connecticut cities and towns, but hasn't yet been implemented on a statewide basis.
