Post-Tropical Cyclone Fausto Discussion Number 43
NWS Central Pacific Hurricane Center Honolulu HI EP062026
Issued by NWS National Hurricane Center Miami FL
500 AM HST Wed Jul 29 2026

It has been 18-21 h since Fausto produced convection that met the
criteria of the Dvorak Technique for tropical cyclone intensity
estimates, with just a few patches of convection occurring well to
the east and northeast of the center. Also, scatterometer data
received after the last advisory suggested the circulation is losing
definition. The cyclone is in an environment of 40-45 kt of westerly
vertical shear and a dry mid-level airmass, and thus significant
convective re-development appears unlikely. Based on these
developments, Fausto is being downgraded to a remnant low pressure
area.

Fausto continues west-northwestward with an initial motion of 290/11
kt. This general motion should continue until the system dissipates,
as the shallow circulation is steered mainly by the tradewind flow
south of the subtropical ridge. The forecast track keeps the
remnants well to the north of the Hawaiian Islands.

The dynamical models forecast the remnant low to persist for another
36 h or so, and after that it should degenerate to a open trough.
This is reflected in the intensity forecast.

This is the last advisory on Fausto. For additional information on
the remnant low please see High Seas Forecasts issued by the
National Weather Service, under AWIPS header NFDHSFEPI, WMO header
FZPN02 KWBC, and on the web at ocean.weather.gov/shtml/NFDHSFEPI.php


Key Messages:

1. Surf generated by Fausto is building westward across the Hawaiian
Islands along exposed east-facing shores and will remain dangerous
today as Fausto passes north of the islands. Large surf and strong
currents will lead to dangerous conditions along exposed shores.
Please consult products from your local weather office.
