Oscar was also the eighth named storm to form since Sept. 24, breaking a record for most named storm formations between Sept. 24 and Oct. 19.

Hurricane Oscar has formed off the coast of the Bahamas, the National Hurricane Center (NHC) said Saturday. The storm poses potential threats to surrounding areas of the southeastern Bahamas and is expected to bring hurricane conditions and produce a storm surge on the Turks and Caicos Islands, with heavy rainfall, the NHC said.

Tropical Storm Oscar formed on Saturday, the 15th named storm of this year’s Atlantic hurricane season and the second in less than a day. It’s expected to bring heavy rain to the Caribbean islands this weekend, including Cuba, which has been facing a nationwide electricity crisis.
