Essex County, New York officials announced a state of emergency from April 6-10, as reported by NBC affiliate WPTZ, in anticipation of the tourist influx and potential cell service disruptions due to the upcoming solar eclipse. A similar declaration was also made in Oswego County, as reported by WSYR.

Several counties and cities in Texas have followed suit by issuing similar declarations, citing concerns about increased traffic and the need to prepare for potential emergencies. The state is expected to experience a surge of over a million visitors during the eclipse, as reported by the Great American Eclipse tracking organization.

Indiana Governor Eric Holcomb issued a state of emergency declaration on March 26, which will remain in effect until 11:59 p.m. on April 9. This measure aims to enhance preparedness for the anticipated surge in visitors, which could potentially hinder emergency response efforts.

Governor Holcomb's executive order referenced Indiana's participation in the Emergency Management Assistance Compact, a nationwide mutual aid program. This program enables states to request assistance or resources from others when a governor declares a state of emergency.

State of emergency declarations can activate various forms of assistance from the Federal Emergency Management Agency (FEMA). These may include individual assistance for small businesses and households, as well as public assistance programs aimed at supporting road systems, public facilities, and other emergency protective measures.

At the county and city levels, such declarations enable local officials to seek assistance from state emergency management agencies. Additionally, both local and state governments have the authority to directly request aid from the federal government if necessary, including the option to petition the president to declare a major disaster, as outlined by FEMA.
