Condition Monitoring Report  
Station Number: VA-RNC-3
Station Name: Roanoke 1.9 SSW
Report Date: 4/24/2025
Submitted: 4/24/2025 2:02 PM
Scale Bar: Mildly Dry
Description:
Decided to do an interim CM report as conditions are worsening. April station rainfall through today, 4/24 is at 1.82" with only 0.03 since the mid-month report. Now about 1 inch below April climatology and 66% of normal. March was also quite dry at 1.65" or ~50% of normal. Water year (Oct. 1 to date) deficit at this site now about 4 inches (-3.96"), or 82% of NOAA normal for the period. The precipitation deficit is evident in local streamflows, many USGS gage sites showing below normal flows. The Roanoke River at Roanoke 7-day flow as of 4/23/25 was 193 cfs or the 11th percentile of all flows for the date (51% of median). Stages are falling and are well into the Below Normal category (10-24 precentile) and bordering on Moderate Hydrologic Drought (6-9 percentile). The only 'bright' spot is reservoir storage at Carvins Cove as of 4/15 which was at -1.1 feet below full pond (97.2% capacity) a -0.4 ft. change since 4/15 report. The US Drought Monitor (USDM) valid as of 4/22/25 continues to show D0 or Abnormally Dry conditions over nearly all of western and central VA with Moderate Drought expanding from the north and the south. Will maintain local Condition in the Mildly Dry category but just barely--there is a lot of warm season to go! April temperatures to date (1-24) are running warmer than normal (+2.6F) increasing ET demand and surface soils are very dry, plants require frequent watering. This will be my last CM report until late May, hopefully things get better while I'm gone!
