San Ysidro, the town this property stands in, in 12 storm reports between 2000 and 2024: 6 flood, 3 flash flood, 1 wildfire, 1 debris flow.
The reports record 3 deaths and 13 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.
San Diego fire department and rescue and U.S. Border Patrol report 8 people trapped in a flooding storm drain between Otay Mesa and San Ysidro. 7 people were helped to safety with one fatality.
A 61 year old man drowned in the Tijuana River Channel on February 6 while attempting to cross the international border, following heavy rain in San Diego. San Diego Fire-Rescue swift water crews pulled the body from the river and despite attempted lifesaving measures, the man was pronounced dead at the scene.
Significant flooding in the Tijuana River Valley resulted in the deaths of a Tijuana man and numerous ranch and farm animals. At least 21 people had to be rescued, including 6 by helicopter. Three men were taken to a hospital and treated for hypothermia. An estimated 70 horses were also rescued. Three horses drowned before they could be rescued and another horse was later euthanized due to a leg injury. Fifteen goats and an unknown number of dogs also died in the flood. One farmer lost $600,000 dollars worth of his crop while another lost $10,000 dollars worth of watermelons. The one human death occurred outside the forecast area in Tijuana, Mexico. The flash flood occurred when both the Tijuana River and a nearby flood control channel became dammed with with sediment, trash, and other debris.
Heavy rain fell across much of San Diego County on January 1st. Per reports from NWS Employees and other trained spotters rainfall totals of 1-3 inches fell across much of the county through the evening hours on the 1st.
