* WHAT...Flash flooding caused by excessive rainfall continues to be
  possible.

* WHERE...Niihau and Kauai.

* WHEN...Through Friday afternoon.

* IMPACTS...Flood prone roads and other low lying areas may be
  closed due to elevated runoff and overflowing streams. Urban areas
  may receive more significant flooding and property damage due to
  rapid runoff.

* ADDITIONAL DETAILS...
  - A surface trough over the Kauai Channel and bring widespread
    showers to Kauai and Niihau before tracking west. An
    approaching upper low will destabilize the atmosphere across
    this area and bring the potential for shower enhancement
    along with isolated thunderstorms that will continue through
    the day Friday. Heavy rain lingering over the same areas on
    Kauai and Niihau may result in flash flooding.
