Redondo Beach, WA
CATEGORY 2
WHAT
No risk of flooding. Although tides will approach about 19.0 feet near 5:24 PM (17:24), the barometric pressure is well above the critical low threshold (around 1009 hPa). NOAA’s flood likelihood remains at 0%.
WHEN
Highest tide near 17:24 PST.
IMPACTS
No anticipated flooding in low-lying areas. No significant travel or property impacts expected.
Compared to historical Category 3 events where NOAA indicated a definite flood probability, current NOAA data shows no sign of elevated flood risk. The barometric pressure is significantly higher than the ~992 hPa typically associated with more severe coastal flooding.
CATEGORY 2
WHAT
No risk of flooding, despite a forecast tide near 19.2 feet at 5:54 PM (17:54). Barometric pressure is around 1008.5 hPa, and NOAA reports a 0% chance of flooding for this date.
WHEN
Highest tide around 17:54 PST.
IMPACTS
No expected flooding or property damage. Normal marine conditions should prevail with no substantial coastal inundation.
Historical comparisons indicate that tides under 21 feet combined with barometric pressures above approximately 1000 hPa rarely correlate with coastal flooding in this area. NOAA’s low flood likelihood further confirms minimal risk.
CATEGORY 2
WHAT
No risk of flooding, even though the tide may reach about 19.4 feet near 6:18 PM (18:18). The barometric pressure around 1005 hPa is not low enough to elevate flood risk, and NOAA forecasts a 0% flood likelihood.
WHEN
Highest tide near 18:18 PST.
IMPACTS
No notable flooding in shoreline zones or vulnerable roadways. Minimal coastal impact is expected.
While 19+ feet tides can be noteworthy, there is no other supporting factor (e.g., very low pressure or strong onshore wind) to trigger flooding. Past Category 4—5 events involved air pressures near or below ~992 hPa, coupled with higher tide levels. None of those conditions are met here, which keeps the category at 2 (no flooding).
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.
