The National Hurricane Center began posting tropical cyclone watches and warnings starting at 0900 UTC on October 18, with a hurricane watch for Barbados. Three hours later, a tropical storm watch was put into effect in Trinidad and Tobago. Late on October 18, a hurricane watch was also issued for Saint Vincent and the Grenadines, St. Lucia, and Dominica, while a tropical storm watch and a warning was extended to include Barbados and Grenada, respectively. At 2100 UTC on October 18, the tropical storm watch that was issued for Trinidad and Tobago was discontinued. Early on October 19, the hurricane watch was extended to include Martinique, Guadeloupe, Antigua, Barbuda, Montserrat, St. Kitts, Nevis, and Anguilla, as well as St. Eustatius, Saba, St. Maarten, St. Martin, and St. Barthelemy shortly thereafter. A hurricane watch in effect for St. Vincent and the Grenadines was soon downgraded to a tropical storm watch; simultaneously, the hurricane watch that was issued for Barbados was canceled. By 0900 UTC on October 19, the hurricane watches in effect for Dominica, Martinique, and Guadeloupe were all upgraded to a hurricane warning. Additionally, the tropical storm watch in Grenada was discontinued.
