Plain English Summary

AI-GENERATED
Requires state emergency managers to integrate non-federal weather forecasts.

The Division of Emergency Management must work, within its existing budget, to fold weather data and forecasting products from outside the federal government into its emergency management decisions, coordinating with federal, state, and local partners.

The division must set standards for evaluating this outside data and procedures for using it, and must actively promote its use across the state's emergency management system.

Every two years, the statewide comprehensive emergency management plan must now evaluate how this new integration affects forecast accuracy, early warning systems, and resilience outcomes statewide.
