Here are several ways in which you can aid those affected by Harvey:

FEMA Administrator Brock Long encouraged Americans who want to help storm victims to connect with the National Voluntary Organizations Active in Disaster (NVOAD) online, which is coordinating donations and volunteers.

Hurricane Harvey relief funds

Houston Mayor Sylvester Turner established the Hurricane Harvey Relief Fund, which accepts tax deductible donations for flood relief victims. The organization will accept checks, money orders, bank wire transfers, stock, corporate bonds and other marketable securities. For donation instructions, click here.
