Hurricane Idalia struck Florida’s Big Bend Wednesday, displacing thousands and bringing strong winds and flooding to the area.

The National Hurricane Center said the Category 3 tropical cyclone has caused “catastrophic” storm surge and damaging winds that spread into southern Georgia. More than 330,000 customers in Florida and Georgia are without power and floodwaters have already shut down roadways and entered homes. Florida Gov. Ron DeSantis said there are no confirmed fatalities as a result of the storm yet, but he has warned residents to prepare for more damage.

“It is likely to cause a lot of damage. That is just a reality. So prepare for that,” DeSantis said during a press conference at the state’s Emergency Operations Center on Tuesday.

As of Tuesday night, nearly 5,000 people had been evacuated to more than 110 shelters, according to Stephanie Fox, a spokesperson for the Red Cross, which is managing 17 of those shelters.

Here’s how you can help those impacted by Hurricane Idalia:

Red Cross

Ahead of the storm, the Red Cross mobilized more than 500 disaster responders along with dozens of specialty response vehicles and truckloads full of supplies and meals, Fox said.

Those wanting to help can visit redcross.org, call 1-800-RED CROSS (800-733-2767) or text the word IDALIA to 90999 to make a $10 donation. People can also write “Hurricane Idalia” in the memo line of a check and mail it with a completed donation form to the address on the form or their local Red Cross chapter. 

The Red Cross is also stocking hospitals in the Florida Panhandle with additional blood products to prepare for impacts to transportation routes in the coming days, according to its website. Fox said blood donations will also be “critically important” because the storm has led to the cancellation of more than a dozen blood drives.

Florida Disaster Fund

DeSantis announced the Florida Disaster Fund, part of the nonprofit Volunteer Florida Foundation, would be activated to support those impacted by Hurricane Idalia. People can donate to the fund, which distributes money to service organizations to support disaster response and recovery, by sending a check in the mail or making a donation here.
