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 Cesar–Douglas
With an unusually strong high pressure area located over The Bahamas, the tropical depression moved westward through the southern Caribbean near the northern coast of South America. Around 1200 UTC on July 25, it struck the island of Curaçao, which reported sustained winds of 45 mph (75 km/h). The observation indicated the depression attained tropical storm status, although operationally the depression wasn't upgraded until the next day, at which point the NHC named the storm Cesar. After crossing Curaçao, the storm moved near or over Guajira Peninsula in extreme northern Colombia. Its proximity to South America prevented significant strengthening, until late on July 26 when the storm reached the open waters of the southwest Caribbean Sea.
On July 27, Cesar attained hurricane status about halfway between Nicaragua and Colombia. Later that day, the hurricane passed over San Andrés island, which is part of a small Colombian archipelago off the east coast of Nicaragua. As Cesar approached Central America, a 17 mile (19 km) eye formed, surrounded by deep convection in the form of an eyewall. At about 0400 UTC on July 28, Hurricane Cesar made landfall just north of Bluefields, Nicaragua with winds of 75 mph (140 km/h). It moved quickly west-northward through the country, weakening to tropical storm status and emerging into the eastern Pacific Ocean by July 29. This made Cesar the most recent tropical cyclone to traverse from the Atlantic to east Pacific basin until Otto achieved the same feat in 2016. In addition, following the dissipation of Cesar–Douglas there was a policy change which determined that future storms would retain their original name upon crossing into another basin. Upon reaching the Pacific, the system was renamed Tropical Depression Seven-E, but in a post-analysis it was determined the cyclone maintained tropical storm status while crossing Central America. Once its status as a tropical storm was confirmed, it was renamed Tropical Storm Douglas. At the time, the agreement through the World Meteorological Organization was for storms to be renamed if they cross from the Atlantic to the Pacific.
