    Remnants Of Iota Discussion Number 21
    NWS National Hurricane Center Miami FL AL312020
    900 AM CST Wed Nov 18 2020

    Although the system still has broad mid-level rotation, synoptic
    observations from Central America show that the surface circulation
    of Iota has dissipated. Its remnants are located somewhere near El
    Salvador.

    Although the remnants of Iota are likely to move into the eastern
    North Pacific during the next day or so, the global models do not
    show regeneration of the system over that basin.

    Iota is still expected to produce very serious flash flooding and
    mudslides, with potentially catastrophic effects, over
    portions of Central America.

    This is the last advisory issued by the National Hurricane Center
    on Iota.


    Key Messages:

    1. Life-threatening flash flooding and river flooding is expected
    through Thursday across portions of Central America due to heavy
    rainfall from the remnants of Iota. Flooding and mudslides across
    portions of Honduras, Nicaragua and Guatemala could be exacerbated
    by saturated soils in place, resulting in significant to
    potentially catastrophic impacts.
