    Tropical Storm Nesat sported a large, dramatic eye on October 19, 2022,
    when the Moderate Resolution Imaging Spectroradiometer (MODIS) on board
    NASA’s Aqua satellite acquired this true-color image. At the time,
    Nesat was losing strength as it battled an intervening cold front as
    the storm moved westward over the South China Sea towards Vietnam.

    Although the system started the day with maximum sustained winds of
    about 60 mph (96.5 km/h), as of 5:00 p.m. EDT (2100 UTC) on October 19,
    Nesat was very close to a Tropical Depression, carrying maximum
    sustained winds of 40 mph (64.4 km/h). By definition, a tropical storm
    carries maximum sustained winds of 39-73 mph (53-117.5 km/h) while a
    tropical depression’s winds are 38 mph (61 mph) or less. According to
    the Joint Typhoon Warning Center (JTWC), Tropical Storm Nesat was
    located 110 miles (178 km) north of Da Nang, Vietnam and was tracking
    northwestward.

    Tropical Storm Nesat is forecast to weaken through the next 24 hours
    and forward motion should slow, bringing landfall over eastern Vietnam
    on October 20-21. It is expected to stall shortly after landfall, then
    dissipate quickly. Parts of central Vietnam are still dealing with
    damage from Tropical Storm Sonca. That storm made landfall on October
    14-15 and brought flooding and landslides. About 3,700 people were
    displaced during Sonca and at least on person died.
