Category 1 · NO FLOODING EXPECTED

Flood Watch

Redondo Beach, WA

Day 1: 2026-09-16

CATEGORY 1

WHAT No flooding risk is expected. Tides are moderate, and near-normal pressure with light winds keeps water levels in a routine range.

WHEN Peak high tides occur mid-morning around 9:54 AM and again in the evening near 8:30 PM.

IMPACTS • No impact anticipated.

REASONING This low category stems mainly from a routine high tide and generally normal atmospheric pressure. Wind influence is minimal. This is similar to the 2026-03-29 Cat 1 event with comparable conditions.

Day 2: 2026-09-17

CATEGORY 1

WHAT Again, no flooding risk. Tides remain modest, with slightly lower-than-average pressure but limited wind effects.

WHEN Morning high tide around 11:00 AM, and a nighttime high tide near 9:12 PM.

IMPACTS • No impact anticipated.

REASONING The moderate tide and near-normal pressure do not favor flooding. Onshore wind is negligible. Similar conditions were seen on 2026-05-10 (Cat 1).

Day 3: 2026-09-18

CATEGORY 1

WHAT No flooding threat. Steady pressure and moderate tide levels indicate routine conditions.

WHEN Main high tide windows occur around 12:30 PM and near 10:06 PM.

IMPACTS • No impact anticipated.

REASONING A modest tide, near-normal pressure, and limited wind contribution keep this day at low risk. This is similar to the 2026-03-25 Cat 1 event.
