, heavy rain fell, and property damage was significant; many homes lost their roofs, and a few even collapsed. In addition, trees were uprooted, and fences destroyed. A recently constructed windmill was also blown away completely. Three schooners, the ''Plutus'', the ''Lovely Flora'', and the ''X.L.'', were blown ashore, although only the ''X.L.'' suffered major damage. Rainfall in San Pedro was also heavy, but high winds were not reported. Parts of the embankment in the city were washed away, causing only around US$100 ($3,100.02 in 2019) in damage. The yacht ''Medora'' was washed ashore. Many reports claimed that the yacht was irreparable, but it was later claimed that the damage was not serious and could be repaired. A barge was destroyed, as was a large portion of the San Pedro wharf. El Monte was buffeted by high winds, damaging corn crops and trees.
