The Leon County Emergency Information Portal (http://www.leoncountyfl.gov/ei/) contains warnings and information for active flood events. Additional information on flood warnings can be heard on local radio and TV stations.
Information provided by various websites can be used to monitor rain events.
The Northwest Florida Water Management District operates rainfall gauges from Jefferson County to Escambia County. Many of the gauges were installed and are operated through a contract with Leon County and the City of Tallahassee. Rainfall in Leon County can vary by a surprising amount from north to south or east to west. These gauges can be viewed at: http://www.nwfwater.com/data-publications/hydrologic-data/district-wide-map-of-rainfall-stations/
The Northwest Florida Water Management District operates water level recorders from Jefferson County to Escambia County. Many of the gauges were installed and are operated through a contract with Leon County and the City of Tallahassee. Water levels typically respond to localized rainfall, which can vary quite a bit across Leon County. The water level gauges can be viewed at: http://www.nwfwater.com/data-publications/hydrologic-data/district-wide-map-of-stage-stations/
The US Geological Survey has monitored water levels on the rivers throughout the nation for decades. The gauge levels are for historic comparison and are NOT adjusted to ground elevation. The Ochlockonee River and the St. Marks River gauge levels can be selected from the Florida WaterWatch site at: http://waterwatch.usgs.gov/?m=real»r=fl
Severe flooding in Leon County often results from tropical storms passing near or through our area. The National Hurricane Center (NHC) provides early warning and tracking information for developing tropical systems. The NHC regularly updates the forecast path of a storm and issues warnings where necessary to protect human lives and property. This information is considered by local emergency management agencies when determining whether evacuations are necessary, for example. The NHC tropical activity information can be viewed at: http://www.nhc.noaa.gov/
The National Weather Service does more than report rainfall totals and issue tornado alerts. The Southeast River Forecast Center monitors rivers in our area for flooding conditions. The highest water level, also known as "crest", will be forecast when rivers are in flood stage. A quick glance at the "River Observations" map at this webpage will inform you about local river conditions: http://water.weather.gov/ahps2/index.php?wfo=tae
