Episode narrativeepisode_narrativeThe remains of Hurricane Michael were preceded in parts of western Virginia by a so-called Predecessor Event (PRE) which brought moderate to heavy rainfall across several counties early on the 11th of October. A deep moisture plume surged north on the periphery of the subtropical ridge over the southeast with the very high precipitable water producing high rainfall rates. The heaviest rainfall from the PRE was concentrated in upper and middle portions of the New River basin and the far upper Dan basin where the amountsl ranged from 2 to 6 inches with isolated higher amounts in the 24 hours ending at 700 AM local time.
Event narrativeevent_narrativeThe automated rain gage located at the USGS Galax River gage site (GAXV2) measured 5.03 inches in 24-hours ending 700 AM local time on the 11th. This value falls into the 90 percent confidence interval (4.74-5.73 inches) for a 25-year recurrence interval event (.04 annual exceedance probability) per NOAA Atlas 2.
