Tropical Storm Harvey has formed "again" in the Atlantic and this time he is heading towards Texas. The storm is currently over the warm waters of the Gulf of Mexico, which is expected to provide a favorable low shear environment. This is good for tropical systems, which is why Harvey is expected to reach hurricane strength just before landfall.
The lack of upper-level steering currents will also make Harvey a slow mover, which will increase the flooding risk around Texas and the surrounding areas. Models are suggesting rainfall totals up to 15" or more along the coast. If you have travel plans be sure to stay up to date and alert family & friends in the Texas area.
