We received round one of this week’s rain Sunday and yesterday. \u00a0I received almost 2 inches at my house on the east side of Athens, GA. \u00a0Tuesday there is a respite before the next deluge begins, although with afternoon heating there is a chance of some showers even today. \u00a0But the radar shows the next mass of rain heading towards Georgia from southern Mississippi and Alabama. \u00a0The NWS Southeast River Forecast Center has an online slide set which explains some of their reasoning for current flood potentials at\u00a0https:\/\/www.srh.noaa.gov\/media\/serfc\/alert\/DOSM_April_14_2015.pdf<\/a>. \u00a0They are a fantastic source of real-time information so be sure to visit their web page whenever flooding conditions are possible.<\/p>\n

If you don’t have a rain gauge, how do you know what amount of rain fell? \u00a0There are a variety of sources online that can give radar estimates or maps of observed precipitation. \u00a0Here are some of the ones I use. \u00a0Note that there are many more, so this is not close to an exhaustive list.<\/p>\n

Radar-estimated rainfall:<\/strong><\/p>\n

NWS local forecast offices<\/em><\/p>\n

Each NWS radar site has a way to visualize accumulated precipitation on its site. \u00a0Here is the one from NWS Peachtree City near Atlanta GA this morning. \u00a0The advantage to this display is that it is available in real time, but it may be less accurate because it has not been calibrated to what local rain gauges collected and sometimes has problems when hail or freezing conditions are present. \u00a0The storm total accumulation does not start at a standard time.<\/p>\n

NWS national radar estimate<\/em><\/p>\n

Each morning the NWS produces a national radar estimate of rainfall for the country, which is available at\u00a0https:\/\/water.weather.gov\/precip\/<\/a>. \u00a0The one for today is below. \u00a0The advantage of this site is that it gives a daily value which can be compared to observations and that it is calibrated to remove some of the issues with ice and heavy rain intensity which can affect the accuracy of the individual radars. \u00a0It also blends all the local radars into one seamless map. \u00a0The disadvantage is that it is not available in real time. \u00a0Their maps show 7 am to 7 am rainfall.<\/p>\n

\"NWS<\/a><\/p>\n

Station-based observations<\/strong><\/p>\n

CoCoRaHS<\/em><\/p>\n

The CoCoRaHS<\/a> network is a network of volunteer weather observers who take rainfall observations each morning around the country. \u00a0They report for 24 hours from roughly 7 am to 7 am. \u00a0I’ve written about them several times before and am a regional coordinator for Georgia. \u00a0 Here is the map of observations for the Atlanta metro area for this morning.<\/p>\n

The Southeast Regional Climate Center has a daily map which shows the midnight-to-midnight rainfall amounts from NWS airport stations at\u00a0https:\/\/www.sercc.com\/perspectivesmap<\/a>.<\/p>\n

\"sercc<\/a><\/p>\n

 <\/p>\n

CRONOS<\/em> is a website from North Carolina State University with data for many locations across the Southeast. \u00a0 They report values from NWS cooperative volunteers as well as some automated networks around the region, not including the University of Georgia network. \u00a0Here is this morning’s map from\u00a0https:\/\/www.nc-climate.ncsu.edu\/map\/?table=daily<\/a>.<\/p>\n

\"cronos<\/a><\/p>\n

In addition, there are data available from individual states’ automated weather networks, such as the University of Georgia network at https:\/\/www.georgiaweather.ne<\/a>t and the Georgia Forestry network at https:\/\/weather.gfc.state.ga.us<\/a>. \u00a0The maps below show the UGA network\u00a0on the left and the Georgia Forestry map on the right. \u00a0Note that the maps from the local networks are based on a smaller number of stations and so may miss some local dry areas or heavier rains in their graphing schemes.<\/p>\n
