| Episode narrativeepisode_narrative | A strong cold front associated with a negatively tilted shortwave upper trough approached the region on October 23rd. Precipitable water rose to near excessive levels for the time of year with 1.44��� on the 12z (8 AM EDT)/23 RNK (Blacksburg) and 1.57��� on the 12z (8 AM EDT) GSO (Greensboro) soundings, with sea-level values of 1.75��� to 2���. These are roughly three standard deviations above the late October climatology and near all-time maxima for the date. Enhanced rainfall rates due to decent instability (for late October) were also expected to develop. Moderate rainfall of 1 to 2 inches had already fall ahead of a cold front that approached in the mid-afternoon. Flood impacts began to occur quickly as the higher rate rainfall moved into the area. The IFLOWS rain gage at Sandy Flats (SDRN7) just southwest of Boone had 2.73��� in a 2-hour period ending at 400 PM, close to a 10-year (0.1 AEP) annual recurrence interval. Flooding was described as 'historic' by some observers ranking close to that seen in Hurricane Hugo in 1989. |
| Event narrativeevent_narrative | Boone 1 SE COOP observer measured 5.95 in 24-hour period ending 8 AM on the 24th. This is the highest ever 24-hour October rainfall at this location since 1980 and at any Boone COOP site dating back to 1929. It was also the 3rd highest 24-hour rainfall for any day at both sites. The annual recurrence interval for this rainfall (per NOAA Atlas 14) was between a 5 and 10-year event (0.2 and 0.1 Annual exceedance probability). |
