Redondo Beach, WA
CATEGORY 3
WHAT
A moderately high tide of around 19.6 ft is expected late morning. Barometric pressure near 1016 hPa is not extremely low but is somewhat lower than on subsequent days, making conditions “close to a flood event and worth monitoring.” NOAA’s official forecast shows a low flood likelihood, yet the tide height warrants attention in historically flood-prone areas.
WHEN
Greatest concern is around the late morning high tide (approximately 10:30 AM to 1:30 PM PST), peaking near 11:36 AM.
IMPACTS
Minor water encroachment into vulnerable shoreline spots is possible; however, widespread property damage is not expected. Low-lying roads and parking areas near the shoreline could see isolated ponding.
• Tide height near 19.6 ft is below thresholds observed in the more severe Category 4 or 5 historical events.
• The barometric pressure, while not high, is still significantly above the very low pressure readings known to coincide with major flood events (below about 992 hPa).
• Winds out of the south (S/SSW) do not typically push as much water onshore as W/NW winds in this region.
• NOAA’s 0.0% flood likelihood aligns with only minor or no flooding, but vigilance is advised given the moderately high tide level.
CATEGORY 2
WHAT
A high tide near 19.6 ft is forecast again around midday, but barometric pressure is notably higher (about 1023 hPa), substantially reducing any flood risk.
WHEN
Peak water levels occur from late morning to early afternoon (around 11:30 AM to 1:30 PM PST), with the highest tide near 12:24 PM.
IMPACTS
No significant flooding is expected in coastal areas, as the higher atmospheric pressure and NOAA’s 0.0% flood likelihood both indicate minimal risk.
• Despite having a tide height comparable to Day 1, the increased barometric pressure further diminishes flood potential.
• Historical Category 3–4 flooding has occurred with either much lower pressure or higher tide levels.
• Current forecasts show little chance of damaging onshore wind effects.
CATEGORY 2
WHAT
Another relatively high tide of roughly 19.4–19.5 ft is expected near midday, matched with continued high barometric pressure (about 1022 hPa). These factors together suggest no flood risk.
WHEN
Late morning into early afternoon (high tide peaks around 1:06 PM PST).
IMPACTS
No notable flooding concerns. Typical minor splashing over very low-lying barriers could occur, but no property damage is anticipated.
• The pressure remains high, which historically corresponds to negligible flood issues even with above-average tides.
• NOAA’s projection remains at 0.0% likelihood, confirming the minimal risk profile.
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.
