Last of the remnants of Guillermo will move away from the region
today before a bit of clearing Sunday into Monday. Generally
light/scattered showers are expected. Next week, current hurricane
Hilda is forecast by the CPHC to move northwestward toward a point
about 150 miles northeast of the Big Island. This represents a
blend of the ECMWF and GFS forecasts, which keeps most of the
moisture in the then likely much weakened system to the northeast
of the island chain. A change to this forecast will result in
modifications to the forecast.
Nevertheless, an increase in moisture is almost assured, with the
ensembles showing a rise in PW values in step with the
deterministic GFS and ECMWF. See no reason to deviate much from a
blend of the two models for next Thu-Sat which will likely keep
moisture around the island chain and precipitation chances high.
