In case you were wondering what role the USA plays.
Here is the status from a FEMA, 9-2-19 situation update:
Aid to the Bahamas
A prolonged period of hurricane-force winds and storm surge continues to impact the north western Bahamas. DHS and FEMA leadership are closely monitoring the situation and remain in coordination with leadership from the U.S. Department of State and the U.S. Agency for International Development (USAID).
USAID is in contact with the government of the Bahamas to determine response needs as Hurricane Dorian continues to impact the islands. The United States Coast Guard, in coordination with the Department of State, has a mutual aid agreement with the Bahamas to provide resources and assist in search and rescue missions. In addition, the American Red Cross has resources and staff in place in the Bahamas and stands ready to assist survivors with emergency sheltering and other immediate needs
