Tornado (TOR) and Flash Flood (FFW)
Effective Tuesday, February 4, 2014, at 1500 Coordinated Universal Time (UTC), NWS Weather Forecast Offices (WFOs) will add a headline in a Tornado Warning (TOR) that includes the terminology TORNADO EMERGENCY, and in a Flash Flood Warning (FFW) that includes the terminology FLASH FLOOD EMERGENCY. These headlines will effectively highlight the potential for large scale loss of life and catastrophic property damage in these rare Tornado and Flash Flood events.
The headlines will be inserted directly following the date/time in the WMO Header, and before the first line that begins: THE NATIONAL WEATHER SERVICE IN xxx HAS ISSUED A. The headline will be preceded by an ellipsis, and followed by an ellipsis. For example,
...TORNADO EMERGENCY FOR MOORE AND SOUTH OKLAHOMA CITY...
...FLASH FLOOD EMERGENCY FOR CENTRAL KENT COUNTY...
These new headlines will duplicate, not replace, the inclusion of TORNADO EMERGENCY or FLASH FLOOD EMERGENCY in the last line of the third bullet, known as the basis statement, of the warning.
Users who receive or provide services based on the parsing of exact text strings are advised to allow for these headlines in their software and system operations. Users are encouraged to use the following test products examples to verify parsing of exact text.
