(Latitude 38° 44′.0 N., longitude 76° 50′.5 or 5h 07m.4 W. of Gr.)April 1–3—A disturbance, which at first seemed insignificant, began near 18h GMT, April 1. At about 06h, April 2, the disturbance became more violent than any recorded here in some time. After 13h the storm again was of only moderate severity until it ended at about 09h, April 3. Two K‐indices of 7 were recorded during the most violent part of the storm; also an index of 6 for the first three‐hour period of April 3.
