Ranked by deaths, injuries, damage and size together.
- Flash Flooding and Flooding in Puerto Rico, September 17 to 21, 2022Hurricane Fiona made landfall on Sunday the 18th around 3:20 PM AST near Punta Toc n in southwestern Puerto Rico. Strong, gusty winds accompanied much of the stronger convection embedded within the hurricane.
- Flash Flood and Debris Flows in Puerto Rico, September 1 to 3, 2008The extreme outer bands of Tropical Storm Hanna impacted Puerto Rio during the first week of September. Hanna's circulation induced a low level flow of south to southwest winds that pushed showers and thunderstorms from the Caribbean waters northward into the island.
- Flash Flooding and Debris Flows in Puerto Rico, May 6 to 10, 2024Saturated soils from the previous rainfall events enhanced the risk of flash and river flooding, as another mid to upper-level trough lingered across the region.
- Tropical Storm and Flash Flooding in Puerto Rico, July 29 to 30, 2020Tropical Storm Isaias affected the area on July 29th and July 30th. Even though the center passed about 100 miles south of the southern coast of Puerto Rico, given that the tropical cyclone was large in size, the associated impacts extended well north and northeast.
- Flash Flooding and Flooding in Puerto Rico, May 1 to 5, 2025Unstable and wet weather conditions were anticipated in early May due to a combination of abundant tropical moisture and a series of upper-level troughs moving over the region.
- Flash Flooding and Debris Flows in Puerto Rico, April 26 to 30, 2025From April 26 through 30, a moist and unstable weather pattern affected Puerto Rico and the U.S. Virgin Islands. The episode began as deep tropical moisture moved into the region from the southeast, interacting with deep-layer troughs and supportive jet dynamics aloft.
- Flash Flooding and Flooding in Puerto Rico, October 25 to 26, 2012Showers and thunderstorms associated with the outer bands of Hurricane Sandy were strong enough to produce moderate to major flooding across the Guayanilla and Caguas area between October 25th and October 27th.
- Flash Flooding and Debris Flows in Puerto Rico, September 24 to 27, 2025The flooding threat increased as a robust tropical wave moved across the region. This wave combined with instability associated with an upper-level trough. As the wave departed, tropical moisture continued to flux into Puerto Rico.
- Flash Flooding and Debris Flows in Puerto Rico, May 5 to 7, 2012Upper level trough combined with ample low level moisture to produce scattered to numerous showers with thunderstorms across Puerto Rico.
- Flash Flooding and Debris Flows in Puerto Rico, September 5 to 9, 2025Tropical moisture associated with a tropical wave and other trade wind perturbations, along with an upper-level trough resulted in the formation of strong showers and thunderstorms.
- Damaging Wind in Puerto Rico, July 21, 2004Several homes reported blown off zinc roofs. Small hail was reported in Aguadilla and Hatillo.
- Damaging Winds in Puerto Rico, July 17, 2010During the early afternoon of Saturday July 17, a squall line affected the grounds of the Olympic Stadium in the City of Mayaguez, where the Opening Ceremony for the the Mayaguez 2010 Central American Games was to be held later during the afternoon.
- Flash Flooding and Debris Flows in Puerto Rico, April 16 to 18, 2026An amplifying mid- to upper-level trough, combined with above-normal moisture, maintained an unstable, wet pattern.
- Flash Flooding and Debris Flows in Puerto Rico, October 25 to 29, 2023Moisture pulled into the region by TC Tammy (by that time well north of the area), in combination with an upper-level trough, a frontal boundary and a pre-frontal trough, produced numerous showers and thunderstorms across the islands.
- Flash Flood and Hail in Puerto Rico, May 11, 2017The proximity of a mid-upper level trough and a surface shortwave trough with abundant moisture provided favorable environmental conditions for the development of thunderstorms and widespread showers over the region.
- Flash Flooding and Debris Flows in Puerto Rico, February 6 to 8, 2024A deep-layered trough along with several frontal boundaries was approaching the Caribbean Islands in the first week of February. The winds became light and from the south-southwest, pulling plenty of moisture from the Caribbean Sea.
- Damaging Wind in Puerto Rico, August 25, 1993A severe thunderstorm affected the city of Mayaguez in western Puerto Rico causing structural damages to several residences.
- Flash Flooding and Debris Flows in Puerto Rico, October 29 to 31, 2024A series of cold fronts and a polar trough increased moisture and instability across the region for the last three days of October. Moisture levels went well above the climatological value, leading to a significant increase in showers and thunderstorms.
- Flash Flooding and Debris Flows in Puerto Rico, April 19 to 21, 2025A mid-to-upper-level trough, in combination with a surface induced trough, produced periods of heavy rainfall that caused flash floods and landslides between April 19-21.
- Flash Flood and Debris Flow in Puerto Rico, May 14 to 18, 2011A broad trough associated with a persistent surface low north of the area and a wide northeast to southwest swath of moisture south of Puerto Rico moved very slowly east and created a highly unstable environment across the local area.
- Damaging Wind in Puerto Rico, April 15, 1993A severe thunderstorms affected the eastern and interior sections of Puerto Rico with heavy rains, strong gusty winds and 0.75- inch-diameter hail. The strong winds tore the roof off of 10 homes in Gurabo and a school in Caguas.
- Flash Flood and Debris Flow in Puerto Rico, August 16 to 18, 2025Major Hurricane Erin moved northeast and north of Puerto Rico and the U.S. Virgin Islands. Erin's Outer Bands and then Feeder Bands still affected the islands, producing strong thunderstorms, gusty winds, and heavy rains across the islands.
- Flash Flooding and Debris Flows in Puerto Rico, May 2 to 5, 2024Puerto Rico observed two events with above-normal moisture and instability from May 3rd through the 9th.
- Flash Flooding and Debris Flows in Puerto Rico, November 9 to 13, 2024A Flash Flood Watch was issued on the second weekend of November, mainly due to a tropical wave moving through the area and a lingering frontal boundary. Saturated soils and moderate to heavy rainfall helped increase the flood and debris flow threat.
- Flash Flooding and Flooding in Puerto Rico, March 24 to 28, 2026A moist and unstable weather pattern affected Puerto Rico from March 24 through March 28, 2026, as a mid- to upper-level trough interacted with abundant tropical moisture and favorable upper-level dynamics.
