The rain we've gotten has been significant and at times rather dramatic, but the really heavy stuff has been to the north. We've gotten a bit over two inches since Monday afternoon, with more to come.
These are big Pacific storms, producing surf far larger than San Diego is accustomed to seeing. From the NOAA:
THE FOURTH AND LARGEST GROUP WILL BE A 15 SECOND - 16 FOOT WEST SWELL, CAUSING BREAKERS OF 13 TO 18 FEET WITH MAXIMUM SETS TO 21 FEET ON FRIDAY AND SATURDAY.
