Alert: Hydrologic Outlook issued April 6 at 6:19AM HST by NWS Honolulu HI

ESFHFO

A significant pattern change is expected to begin Tuesday as an
upper level disturbance and surface low pressure system evolve
northwest of the islands. This system is expected to draw deep
tropical moisture northward over the state, leading to an extended
period of moderate to breezy southerly winds, increasing chances for
widespread rainfall, and renewed flooding concerns from late Tuesday
through next weekend.

Now is a good time to prepare for possible flooding impacts:

-Clear gutters, storm drains, culverts, and drainage areas of debris
to improve water flow

-Move valuable items out of low-lying or flood prone areas

-Check pumps, generators, and emergency equipment to ensure they are
operational

-Take stock of emergency supplies, including food, water,
medications, flash lights, and backup power sources

-Review family emergency plans and check on neighbors and family.
especially those in flood-prone locations.

Residents living near stream, rivers, gulches, valleys, ravines and
flood-prone areas should remain especially alert and prepared to
move to higher ground if flash flooding develops.

This outlooks will be updated daily or sooner if needed.
