(CNN) -- The remnants of Hurricane Isaac are moving north but only after drenching some areas of the Gulf Coast with more than 20 inches of rain and displacing thousands of residents.
"People have in their mind that the hurricane is over, but there is still huge flood problem," said Daphne Hart, a Red Cross spokeswoman. "This is an area still in the throws of an ongoing disaster, and people need help."
The Red Cross is operating 60 shelters in six states and is prepared for them to remain open for as long as needed. 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.
The Red Cross is also preparing for a potential blood shortage in areas affected by Isaac, as the storm forced the cancellation of multiple blood drives in the region. Eligible donors in unaffected areas can schedule an appointment to give blood by calling 1-800-RED CROSS or visiting RedCrossBlood.org.
As floodwaters begin to recede, weary residents will return home to start the cleanup process. Local volunteers can donate their time and professional skills to the recovery.
