Bloom Description

Volunteer reports: Overcast, smoky (smoke in air), Heavy rain on 13 July - more than an inch; some wind and waves less than 6 inches. 13 July -- more than an inch. Very different from the HAB of last week -- this was harder to see -- lines of green dots on the surface. Dissipated fairly quickly -- I watched for about 2 hours and it was gone by 3pm. Probably moved by wind and spread out by the waves,
