If some of the rainfall predictions come true, this will be close to a "100-year" event, if not more. This website shows where it will flood near you if you type your address in the box. If it's more than a 100-year storm, the blue shaded area will be even bigger. Think in terms of roads washing out between you and supplies, if you aren't in the floodplain, but are trapped between two floodplain areas. Develop a plan with your family if needed. Best wishes to all. We're in the enhanced risk zone of the same storm all the way out here in north central Texas.
