    4-10: Elsa, the earliest fifth named tropical cyclone in Atlantic Basin history, produced heavy rain and gusty winds in parts of Florida before soaking the Atlantic Seaboard. Briefly a hurricane twice during its life cycle, Elsa crossed Cuba on July 5
    and passed west of the Florida Keys on July 6. As a tropical storm, Elsa made landfall on the Gulf Coast in Taylor County, FL, on July 7, later moving roughly parallel to the Atlantic Coast. Elsa made the transition to a post-tropical cyclone on July 9
    along the northern Atlantic Coast. Meanwhile, showers and thunderstorms—related to the monsoon circulation and a slow-moving storm system, respectively—dotted the Southwest and Midwest.

    In Maine, it was the wettest Independence Day on record in locations such as Bangor (2.00 inches) and Augusta (1.18 inches). Dalhart, TX, also experienced its wettest July 4 on record, with 1.85 inches. Meanwhile, hail was reported on July 4 in Colorado

    above flood stage on July 11) achieved its highest crest since July 1990. Back in Florida, the core of Elsa passed close enough to the Florida Keys on July 6 to generate a wind gust to 70 mph in Key West. Two days later, the remnants of Elsa resulted in
    daily-record amounts for July 8 in Raleigh-Durham, NC (2.52 inches); Georgetown, DE (2.45 inches); Florence, SC (2.30 inches); and New York’s Central Park (2.27 inches. On July 9, Central Park reported another daily-record sum (2.06 inches). Other

    more, fell from the middle Mississippi Valley into the lower Great Lakes region. Meanwhile, the interaction between the monsoon circulation and a cold front delivered scattered to widespread showers across the Plains and Southwest, although rainfall

    Dozens of wildfires continued to burn from northern California to the northern Rockies, with containment efforts hampered by heat, erratic winds, and drought-cured vegetation. Oregon’s third-largest wildfire in modern history, the Bootleg Fire, has
    burned more than 400,000 acres of timber and brush. California’s largest active blaze, the Dixie Fire, has charred nearly 200,000 acres only about 15 miles northeast of the town of Paradise, which was devastated by the Camp Fire in 2018.
