FCC Approves New Emergency Alert System “Event Codes” for 2017 Hurricane Season

The FCC has added three new “event codes” to the Emergency Alert System (EAS) for the 2017 hurricane season. The new rules apply to EAS and NOAA Weather Radio (NWR). Two of the EAS codes correspond to a potential Storm Surge Watch/Warning. The National Weather Service (NWS) is still developing and seeking comments on a Storm Surge Watch/Warning for operational use in 2017. The new codes are:

Extreme Wind Warning (EWW): The EWW is an existing operational warning NWS uses for advance notice of sustained surface wind speeds of 115 MPH or greater during major hurricanes. All NWS Gulf and East Coast Weather Forecast Offices (WFOs) issue the EWW.

Storm Surge Watch (SSA): The NWS may issue an SSA for the gulf and east coasts when life-threatening inundation is possible from rising water moving inland in the specified area, generally within 48 hours. Weather forecast offices could issue the SSA for tropical, subtropical, or post-tropical cyclones. A WFO may issue the watch even earlier, when conditions such as tropical storm-force winds might limit response time for evacuations or other action. A WFO may also issue the watch for locations that could be isolated by inundation in adjacent areas.

Storm Surge Warning (SSW): WFOs may issue an SSW for the gulf and east coasts when tropical inundation is more imminent — generally within 36 hours. NWS may issue a warning when other conditions, such as the onset of tropical storm-force winds, are expected to reduce the time available to evacuate or take other actions. Like the watch, NWS may issue the warning when an area could be isolated by inundation.
