    On July 18, 2022, the sixth named storm and the fifth hurricane of the
    Pacific Hurricane Season was spinning off the coast of Mexico. The
    Moderate Resolution Imaging Spectroradiometer (MODIS) on board NASA’s
    Terra satellite acquired a true-color image of Hurricane Estelle on
    that afternoon. At that time, the slightly asymmetric storm sported a
    cloud-filled eye and convective bands northeast of the center were
    bringing rain to Mexico’s Socorro Island. Near the same time, Hurricane
    Estelle was carrying maximum sustained winds of about 80 mph (129
    km/h), placing it as a Category 1 storm on the Saffir-Simpson Hurricane
    Wind Scale. That was just 5 mph (8 km/h) down from storm’s peak of 85
    mph (137 km/h) reached on the afternoon of July 17.

    On July 15, the National Hurricane Center (NHC) issued the first
    advisory on the system, which was then a tropical depression sitting
    about 345 miles (555 km) south of Acapulco, Mexico. Later that same day
    the storm strengthened and was named Tropical Storm Estelle when
    maximum sustained winds reached 40 mph (65 km/h). On the evening of
    July 16, maximum sustained winds picked up to measure 80 mph (129
    km/h), earning hurricane status for Estelle. Although expected to
    intensify rapidly, Estelle began to encounter wind shear. It was able
    to reach peak strength on July 17 but struggled to maintain strength
    through the next day. By the morning of July 19, Estelle had once again
    become a tropical storm.

    At 11:00 p.m. EDT July 19 (0300 UTC on July 20), the NHC advised that
    Tropical Storm Estelle was located at 20.2 N and 118.0 W, or about 550
    miles (890 km) west-southwest of the southern tip of Baja California,
    Mexico and was moving west northwest at 14 mph (22 km/h). Estelle was
    maintaining maximum sustained winds of 65 mph (100 km/h).

    Tropical Storm Estelle is expected to gradually weaken until it becomes
    a post-tropical remnant low, likely on July 21. It is posing no threat
    to land.
