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 quickly strengthened into a hurricane Saturday afternoon after becoming a tropical storm near the Turks and Caicos earlier that morning. Meanwhile, Tropical Storm Nadine made landfall near Belize City around noon.

Tropical Storm Nadine is expected to bring flash floods to Mexico, Guatemala and Belize, as another storm system forms in the Caribbean Sea.
