ESFHFO
Southerly winds associated with low pressure developing northwest of
the islands will draw a very moist tropical airmass northward early
next week. This will bring periods of heavy rain and a risk of flash
flooding. The most likely period for significant impacts is
Wednesday night through Thursday night. However, afternoon shower
development over island interiors on Tuesday may be heavy as well.
The duration of flooding potential remains less certain than usual
as deep moisture remains over the state into the middle of April
leading to potential for additional waves of heavy rain next weekend
or beyond.
Now would be a good time to clear storm drains, culverts, and other
drainage areas of debris to help reduce localized flooding.
This outlook will be updated daily or sooner if needed.
