Harvey made landfall on August 25 near Rockport, Texas, as a Category 4 storm. A state of emergency has been declared in 30 counties, seven counties are under evacuation orders, and a major disaster declaration has been signed by the president. Several hundred thousand are without power, several thousand have been displaced to shelters, and search and rescue efforts are ongoing.
