5/29/2013 9:05 AM Was raining lightly, then hail started, then heavier rain. Heaviest rain started about the same time the hail stopped. Most hail about 0.2" on snow scale ( center- to -center of black indicators) Groundcover nearly whitened, but some spacing between, and no buildup. Could hardly detect any hail in taller lawn, only on walks, ground cover (redwood bark). NA Rice Rice White Ice 1min no damage Continuous True After rain Same time as smaller hail
