Officials say 19 Iowa Army National Guard soldiers are deploying Monday for Hurricane Irma missions with four helicopters.
The Iowa soldiers will come from units based in Boone, Davenport, Iowa City and Waterloo.
The Guard says the Iowans will move supplies, equipment and people and support searches and rescues.
The storm is pushing inland, hammering Florida with winds and floodwaters that create hazards for rescuers trying to help beleaguered residents.
