1899 San Ciriaco hurricane
Hurricane San Ciriaco set many records on its path. Resulting in at least 3,369 deaths in Puerto Rico, the storm was the deadliest hurricane to hit the island and the strongest at the time, until the Hurricane San Felipe Segundo made landfall in 1928 as a Category 5 hurricane. It was also among the deadliest Atlantic hurricanes ever recorded.
Hurricane Maria
The storm made landfall on Puerto Rico on Wednesday, September 20, near the Yabucoa municipality at 10:15 UTC (6:15am local time) as a high-end Category 4 hurricane with winds of 155 mph (250 km/h). A sustained wind of with a gust to was reported in San Juan, immediately prior to the hurricane making landfall on the island. After landfall, wind gusts of were reported at Yabucoa Harbor and at Camp Santiago. In addition, very heavy rainfall occurred throughout the territory, peaking at 37.9 inches (962.7 mm) in Caguas. The eyewall replacement cycle that caused María to weaken to Category 4 strength also caused the eye to triple in size as the diameter expanded prior to landfall. This change in size caused the area exposed to high-intensity winds on the island to be far greater. Widespread flooding affected San Juan, waist-deep in some areas, and numerous structures lost their roof. The coastal La Perla neighborhood of San Juan was largely destroyed. Cataño saw extensive damage, with the Juana Matos neighborhood estimated to be 80-percent destroyed. The primary airport in San Juan, the Luis Muñoz Marín International Airport, was slated to reopen on September 22.
