Category 2 · NO FLOODING EXPECTED

Flood Watch

Redondo Beach, WA

Day 1: 2026-09-13

Category 2

WHAT
Forecast calls for Category 2 conditions, driven primarily by a moderately high tide. Air pressure is only slightly below normal, and onshore winds are minimal. No significant flooding is expected.

WHEN
Peak risk around the morning high tide near 7:06 AM and again in the early evening around 7:00 PM.

IMPACTS
• No impact anticipated.

REASONING
The moderately elevated tide is the main factor, with a small contribution from slightly below-normal pressure. Onshore winds are negligible this day, keeping overall risk low.

Day 2: 2026-09-14

Category 2

WHAT
Another Category 2 day, once again led by the tide as the main contributor. Winds remain light, and pressure sits near or slightly above normal, keeping flood potential minimal.

WHEN
Peak risk near the morning high tide around 8:00 AM and the evening high tide near 7:30 PM.

IMPACTS
• No impact anticipated.

REASONING
Slightly elevated tide is the primary driver, with pressures well within normal ranges and light onshore winds contributing little. Overall conditions remain benign for flooding.

Day 3: 2026-09-15

Category 1

WHAT
A lower Category 1 day, though there is some possibility of reaching Category 2 depending on pressure and wind shifts. Overall, tide influences are smaller than previous days.

WHEN
Peak risk around the high tides near 8:54 AM and 8:00 PM.

IMPACTS
• No impact anticipated.

REASONING
Both tide and near-normal pressure contribute modestly, while the wind offers a slight negative effect, keeping the day at Category 1. However, there is about a 50% model chance of reaching Category 2 if the less favorable pressure scenario materializes. This forecast is similar to the 2026-03-01 Cat 1 event.
