200 PM PDT Tue Aug 01 2017

Irwin consists of a tight swirl of low clouds devoid of deep
convection. On this basis, the system has been declared a remnant
low in this advisory. Data from a recent ASCAT indicate that
wind are still 30 kt to the north and east of the center. The low
is forecast to move toward the northwest about 7 kt toward cooler
waters until dissipation is a day or so.

This will be the last advisory issued by NHC on this system.
