MIAMI, United States (AP) — Spared from the wrath of Hurricane Dorian , people in South Florida are donating water, food and household supplies in a relief effort spearheaded by descendants of some of Miami’s earliest settlers from The Bahamas.

Floridians showed up in droves Tuesday to give cans of food, bottles of water and boxes of diapers to members of two historically black churches who were sorting them before they were to be flown to the devastated islands of Abaco and Grand Bahama.

“We have to channel all that anxiety into something positive,” relief coordinator Jonathan Archer said. Archer is the former head of a parish in Long Island, Bahamas, and current rector of the Christ Episcopal Church in Miami’s historic Coconut Grove neighbourhood, some of whose first settlers hailed from the Bahamas.

Some of the volunteers were frantically trying to text cousins, uncles, aunts and nieces who braved the powerful storm in their island homes. Few had any luck Tuesday.

“I am grateful that we weren’t hit but the severity of the damage in Abaco and Freeport just breaks my heart,” said Diane Alexander, a 57-year-old retired teacher who has cousins in Nassau. Alexander bought provisions for Dorian then decided to donate them when the storm no longer threatened a direct hit on Florida.

Practically parking over a portion of the Bahamas for a day and a half, Dorian pounded Abaco and Grand Bahama with winds up to 185 mph (295 kph) and torrential rain, ripping apart homes, trapping people in their attics, and killing at least seven people. Government officials said Wednesday that they expect the death toll to rise.

The storm finally moved into open waters before moving northwest, and by Wednesday morning it was moving parallel to the northeastern coast of Florida with winds of 105 mph (169 kph). Florida state Representative Shevrin Jones, who was asking people to donate, said one of his extended relatives is an officer with the Bahamas immigration agency and had been working as a first responder. Jones tweeted a screenshot of a WhatsApp message he received from the relative, who said she and her rescue team had found family members curled up together, all of them dead.
