Public Information Statement
National Weather Service Tallahassee FL
802 PM EST Wed Feb 15 2017 /702 PM CST Wed Feb 15 2017/

To: Emergency management officials, news media, and other users.

Effective Thursday, March 16, 2017 the National Weather Service
in Tallahassee will modify the flood stage levels for the
Choctawhatchee River at Bruce [SR-20] (BRUF1) to better reflect
impacts from flooding along this portion of the river.

These new flood levels are:

Action Stage 11 feet (up 1 foot)
Minor Flood Stage 14 feet (up 1 foot)
Moderate Flood Stage    17 feet (up 3 feet)
Major Flood Stage 20 feet (up 3.5 feet)

This location is a flood only forecast point, which means that
forecasts are issued for this location whenever the river is
expected to reach or exceed action stage within the next five
days. These forecasts are issued by the Southeast River Forecast
Center in Peachtree City, Georgia. River flood warnings for this
location are issued by the National Weather Service in Tallahassee
whenever the river is expected to exceed flood stage.

These updated flood stages were a direct result of analysis of
historical floods at this location, dating back to 1928, review of
flood impacts in the area, feedback from the Washington and
Walton County Emergency Management Agencies, and information from
the Florida Department of Transportation.

A set of statements have been developed that communicate impacts
along the Choctawhatchee River at Bruce. These are:
