Virginia Precipitation and Stream Flow for the 7-day Period Ending October 28, 2014

Below are images showing precipitation in the southeastern United States and stream flow in Virginia over the seven-day period ending October 28, 2014. The Virginia Water Resources Research Center thanks the agencies mentioned below for providing precipitation and stream-flow information and images. For monthly reviews of precipitation, stream flow, and drought, please see the News Grouper posts available at this link: http://vawatercentralnewsgrouper.wordpress.com/?s=Monthly+Water+Status.

Precipitation

The following maps show southeastern U.S. precipitation amounts over the past seven days (top map), and the percent of normal precipitation for the given location at this time of year (bottom map).  The maps were accessed on 10/29/14 from the National Oceanic and Atmospheric Administration’s (NOAA) Southeast Regional Climate Center, located at the University of North Carolina in Chapel Hill; online at http://www.sercc.com/climateinfo/precip_maps. As of 10/29/14, these data are provisional (needing to be verified for accuracy and subject to possible revision).

Stream Flow

Average Virginia stream flow over week ending October 28, 2014, is indicated in the map below, from the U.S. Geological Survey WaterWatch for Virginia (online at http://waterwatch.usgs.gov/classic.php?m=pa07d&r=va&w=mv01d%2Cmap, accessed 10/29/14). The map compares the previous week’s average stream flows at about 140 stream-gaging stations (in Virginia and just beyond the state border) to the normal flow levels for that week over the historical record for each gaging station. The color codes/percentile classes used by USGS to compared flows to historical records for the month are as follows:

Severe Storm Reports from the Southeast and Midwest on October 13, 2014

On October 13, 2014, the National Weather Service/Storm Prediction Center received over 330 preliminary (not yet verified) reports of severe weather (tornadoes, high winds, or large hail) from southeastern and lower Midwest states, from the same weather system that brought wind, rain, and tornado watches to Virginia on October 14 and 15.  The Storm Prediction Center’s map of storm reports on October 13 (as of 10/15/14), is shown below.  For the current day’s storm-report map and map archive, plus various prediction maps and tools, visit the Storm Prediction Center’s Web site at http://www.spc.noaa.gov/.

Satellite Photos of Frontal System and Hurricane Gonzalo on Either Side of U.S. East Coast as of Early Afternoon on October 14, 2014

The first photo below is an infrared satellite photo showing both the large frontal system that was approaching Virginia as of the early afternoon of October 14, 2014, and–just on the right edge–part of Hurricane Gonzalo, which was just north of Puerto Rico at that time.  The second photo below is a better shot of Hurricane Gonzalo; according to the National Hurricane Center, at http://www.nhc.noaa.gov/, Gonzalo was expected to cross over Bermuda and then turn away from the Atlantic Coast by Friday, Oct. 17.  Both photos were as of 1:15 p.m. EDT (1715 Z or Greenwich Mean Time shown on the photos), and both were taken from the National Oceanic and Atmospheric Administration (NOAA) Web site at http://www.goes.noaa.gov/browse.html.
