Recommendation from Joplin MO Service

Assessment• The NWS should collaborate with

partners throughout the weather enterprise to provide a better coordinated warning message. Guidance should be developed to assist partners in the development of local warning systems and siren strategies that work in conjunction with the NWS warnings rather than independent of them.

We need to get sirens and weather radio consistent with the polygon warnings

•Midland Radio will be conducting a test in northern Alabama soon with the goal of accelerating the delivery of site specific weather radios – Bruce

•MCDEMA…MEMA…NWS are forming a team to develop recommended siren policies for the state
