Miriam is forecast to continue weakening as it moves well
northeast of Hawaii.  Trades will be on the lighter side as the
upper low drifts to the northwest over the weekend into early next
week past 20N/150W. Mainly light windward/mauka showers are
expected today into early this week.

During Tuesday, both the GFS and ECMWF have an increase in
available precipitable water, so amounts and coverage of showers
increase.
On Wednesday, the trend reverses with drier air forecast to move
across the islands. Then later in the week we will be tracking the
progress on Norman and its potential any impacts on Hawaii.

Please consult the latest information from the the Central Pacific
Hurricane Center on Miriam, and the NHC on Norman and Olivia.
