Followup: the rain has been near constant and widespread much of the day into this evening. There has been no thunder/lightning/wind. Just rain, rain, rain. Sometimes heavy, sometimes moderate or light. Then the heavy would return. Lots of street flooding, made worse this evening by a high tide. On radar, the rain area seems to be stuck with moisture continuing to converge on this area from both the gulf and Atlantic.
