Oceanside, the town this property stands in, in 28 storm reports between 1999 and 2025: 5 funnel cloud, 5 flood, 4 thunderstorm wind, 4 heavy rain.
The reports record 2 deaths and 8 injuries. Each account below is quoted exactly as the forecast office
filed it, from the NOAA Storm Events Database, and each date
opens the federal record of that event.
In Oceanside, lots of small branches and pots were knocked over and a 12 foot shed was tossed approximately 100 feet, based on where it was located originally and the scrape marks where it landed on the street. At least two vehicles were damaged, one with a side mirror damaged by the shed and another had a large tree limb approximately 4 to 6 inches in diameter that broke the window. At least six screens were knocked off on the windows of the homes. And very unique damage done by pinecones from large trees just to the west which left large scrape marks on the side of stucco. Based on the damage, winds are estimated to be 45 to 50 mph in the localized three or four block area.|Downed trees were blocking the roadway on Via de Santa Fe and large palm tree branches were in the number 4 lane of southbound Interstate 5 at Harbor Drive according to California Highway Patrol.
