(CNN) -- Residents along the Gulf Coast continue to get pounded by heavy winds and unrelenting rain from Tropical Depression Isaac, an eerie reminder of Hurricane Katrina, which pummeled the Gulf Coast seven years ago.
Relief organizations are on the ground, providing food and shelter for those displaced from their homes.
"We're still very much in the middle of a major storm," said Daphne Hart, a Red Cross spokeswoman. "The flooding is a huge concern."
The Red Cross has deployed 2,400 disaster workers from Florida to Texas. On Wednesday night, more than 4,700 people spent the night in one of 80 shelters open across seven states.
"We have nearly 200 emergency response vehicles that have been prepositioned in safe areas along the Gulf Coast," Hart said. "And as soon as it's safe to do so, those vehicles as well as disaster assessment teams will be canvassing the area, trying to determine what the needs are.
"It could be anything from serving people hot meals as they're in their home trying to clean up, distributing clean-up kits with items such as rakes, shovels, gloves and trash bags, and just trying to get people back on their feet."
To assist the Red Cross in its efforts, you can donate by visiting the website, calling 1-800-RED CROSS or texting "REDCROSS" to 90999 to make a $10 donation.
If you or a loved one are in one of the affected areas, you can also let people know you are safe by registering on the Red Cross' Safe and Well page.
The Salvation Army is building up emergency response teams and supplies in affected areas along the Gulf Coast. It has 24 mobile feeding units and a 54-foot field kitchen that can provide up to 31,000 meals.
The organization has already provided 3,000 meals, 20,000 drinks and counseling to those in need.
Along with providing food and water for storm victims, the Salvation Army will be on hand to assist in long-term recovery.
"Once the storm passes, folks are going to need to get back into their homes. They're going to need to start the long journey of repairing and replacing the damage that's been done by the storm," said Maj. Terry Ray, Mississippi Gulf Coast area commander. "The Salvation Army comes in with cleaning kits and supplies.
"During that time, the Salvation Army mobile kitchens will continue to roll out. We'll do it as long as people need us. We will continue to feed and roll out cleaning supplies and materials so people can get back to where they were before the disaster hit."
