Numerous reports and pictures/videos were posted on Twitter, with flooding noticeable in parking lots and within business districts. Westport appeared to be hardest hit, with several businesses experiencing flooding in the Marina District. Hazardous ocean conditions led to copious amounts of gravel to build up over Half Moon Bay.
