Flash Flood Watch begins Wednesday afternoon for Kauai and Oahu
Tracking a typhoon swell building over west shores

We are tracking a change in our weather pattern by Wednesday as a weak front coupled with an upper level disturbance sweeps over this state. This will set up shop for a wetter pattern. Flash Flood Watch begins Wednesday afternoon for Kauai and Oahu as the ingredients comes together for the possibility of heavy rain over the western end of the state.

This approaching front, combined with that upper-level disturbance will support increasing rainfall chances by Wednesday, which could linger into Thursday.

Then the trade winds make a comeback as we head into the weekend. That will mean, more stable conditions for us plus drier trade wind weather resuming Friday into Saturday.

Let’s talk surf, the NWS currently has NO ocean alerts up. We are tracking a slight boost in swell energy on north and west shores dues to Hagibis. But nothing too significant.

An upper level low forming to the northeast of the islands Tuesday is forecast to move to the southwest, and by Thursday be southwest of the islands. This upper level feature will help to enhance shower activity, and could provide enough instability for some thunderstorms.
