Joe Biden has declared New Mexico a disaster area. A wildfire has torched 250 square miles (647 square kilometres) over recent weeks. Firefighters slowed the advance of the largest wildfire in the USA as heavy winds relented on 4 May. Biden approved a disaster declaration that brings new financial resources to remote stretches of New Mexico devastated by fire since early April. Representative Teresa Fernandez announced this declaration during a briefing by the Forest Service about containing the sprawling wildfire in high alpine forest and grasslands at the southern tip of the Rocky Mountains. Aeroplanes and helicopters are dropping fire retardant as ground crews clear timber and brush to starve the fire along crucial fronts such as the small New Mexico city of Las Vegas and other villages scattered along the fire’s shifting fronts.
