UPDATE, 10:25 AM: Organizers of Hand in Hand: A Benefit For Hurricane Harvey Relief, scheduled to be broadcast simultaneously on ABC, CBS, NBC, Fox and CMT on September 12, are extending a helping hand to those who may be affected by Hurricane Irma.

“Due to the impending possibility of Hurricane Irma, the Hand in Hand Hurricane benefit has now made arrangements and is prepared to expand its beneficiaries of the September 12th telethon to also include those who may be affected by Hurricane Irma in addition to those affected by Hurricane Harvey,” organizers said in a statement. “We are prepared to help in any way we can.”

Hurricane Irma, currently a Category 5, is one of the most powerful Atlantic storms ever recorded. Packing winds of 185 mph, the storm is on track to pass near or just north of Puerto Rico later today and forecasts show it could turn toward Florida over the weekend.
