| Episode narrativeepisode_narrative | Hurricane Michael made landfall along the Florida panhandle as major hurricane (Category 4 on the Saffir-Simpson scale) on Wednesday afternoon, October 10th, 2018, then tracked northeastward with the northern portion of the storm circulation tracking across portions of Southside, Virginia Thursday afternoon, the 11th. A deep flow of tropical moisture into the Appalachians and central mid Atlantic region ahead of the storm began to generate excessive rainfall across portions of the region as early as Wednesday evening, mainly along the Interstate 77 corridor, causing some degree of flash flooding and otherwise saturating the ground even before the arrival of the rainfall directly associated with Michael.||As the storm circulation approached on Thursday, a cold front moving in from the west and interacted with the storm and enhanced rainfall especially east of Interstate 81. Widespread rainfall amounts of 4 to 8 inches were reported, along with local amounts over 10 inches, mainly from the mountains of North Carolina up through Southside Virginia. This resulted in significant flash flooding with flash flood emergencies issued for the city of Roanoke, as well as Roanoke County, and southern Pittsylvania county including the city of Danville. Unfortunately, there were five fatalities as vehicles were swept away by flash flood waters in Pittsylvania County, Danville, and Charlotte County, Virginia.||The massive volume of water also then generated rapid rises on rivers including the New, Roanoke, and Dan. Major flooding was reported at several river gage locations along with a couple of record crests. There were a few landslides reported as well, blocking roads and in one case destroying a shed.||In addition, as the northern portion of the storm circulation moved across the Piedmont, bands of heavier rains/convection developed and mixed strong winds down to the surface. Many trees were blown down in the water logged soil especially across Pittsylvania, Halifax and Charlotte counties of Virginia where rainfall was heaviest. Despite some initial reports of tornado sightings, damage surveys revealed no conclusive evidence of tornadic circulations and judged damage was caused by straight line winds. |
| Event narrativeevent_narrative | The COOP observer at Keysville 2 S (KYSV2) measured 9.02 inches for the 24-hours ending at 700 AM local time, October 12, 2018. This was the highest 24-hour rainfall amount at this station with partial data back to 1979. The old record was 5.50 inches in July, 2005. In addition, the 9.02 inches is the 3rd highest 24-hour amount for any COOP station in the climate record for the NWS Blacksburg. According to the observer, most of this rain fell in about a 3.5 hour period on the afternoon of the 11th. For the 24-hour duration 9.02 inches falls into the 90 percent confidence interval (8.19-10.2 inches) for a 200-year (.002 annual chance event). For a duration of even 6 hours (being very conservative) the rainfall frequency was in excess of the 1,000 year event (.001 annual chance). |
