Redondo Beach, WA
CATEGORY 2
WHAT
Tides will reach an estimated peak near 19.2 ft in the early morning hours, with relatively high barometric pressure of around 1018 hPa. No substantial flooding is expected.
WHEN
Highest tidal levels expected around 4:00–5:00 AM PST.
IMPACTS
Because of the higher pressure and a calm wind direction from the south/southwest, no flooding impacts are anticipated. Low-lying areas along the shoreline should remain unaffected.
Compared to historical Category 3 events (e.g., 12/27/2023), these tides are higher but the barometric pressure is much higher than those past more concerning events, and NOAA indicates a 0% flood likelihood for this date. These factors support a Category 2 (no risk of flooding) classification.
CATEGORY 3
WHAT
Tidal peaks may approach or exceed 19.5 ft, coinciding with moderately lower barometric pressures (~1009 hPa). This combination is close to levels where flood events have occurred historically, so it is worth monitoring, though widespread damage is unlikely.
WHEN
Two notable high tides: around 4:30–5:00 AM PST and another midday/early afternoon peak around 3:00 PM PST.
IMPACTS
Due to somewhat lower pressure, there may be localized ponding or minor saltwater intrusion in extremely low-lying areas. Most infrastructure should remain unaffected, but marinas and waterfront walkways may see some minor encroachment.
Historically, tide levels near 19–20 ft can become a concern when paired with very low pressures (near or below 992 hPa). Here, despite the tide height, the pressure is still not as low as in past Category 4 events. NOAA’s 0% likelihood supports the conclusion that any flooding, if it occurs at all, would be minor.
CATEGORY 3
WHAT
Projected tide heights could exceed 19.7 ft, with barometric pressure dipping to around 1000–1001 hPa. Conditions are “close to a flood event” and warrant careful observation.
WHEN
Early morning high tide near 5:00 AM PST and a later peak approximately 3:30–4:00 PM PST.
IMPACTS
While still unlikely to cause severe flood damage, lower atmospheric pressure and higher tides raise the possibility of brief minor flooding in coastal spots or parking areas directly abutting the shoreline. Most roads and structures should remain safe.
Compared to historical Category 4 events (e.g., tide at or above 20+ ft coupled with pressures below ~993 hPa), this scenario remains less severe. NOAA’s flood likelihood remains at 0%. Nonetheless, local wind shifts and onshore breezes can intensify wave action, so monitoring is advised.
You should monitor later forecasts and be alert for possible Flood
Warnings. Those living in areas prone to flooding should be prepared
to take action should flooding develop.
Categories 1-2: No risk of flooding.
Category 3: Close to a flood event and worth monitoring.
Category 4: Flooding is likely however, it is uncertain if this will cause major property damage.
Category 5: Likely to flood and cause property damage.
Categories 6-7: Extremely high risk of flooding and property damage.
