Redondo Beach, WA
CATEGORY 2
WHAT
No significant flood risk is expected. High tides could reach approximately 19.6 ft in the early morning, but barometric pressure remains relatively high (above 1010 hPa), and NOAA flood likelihood is extremely low (0.1%).
WHEN
Highest risk window around the morning high tide (approximately 05:30 AM PST).
IMPACTS
No flooding is anticipated. Normal tidal action along the shoreline, with minimal or no coastal inundation expected.
On 12/18, the barometric pressure near the peaks of high tide is around 1017.7 hPa and 1012.7 hPa for the afternoon. Both values are significantly higher than the low-pressure conditions typically associated with notable coastal flooding. Historical Category 3 or 4 events often involved lower barometric pressure (below ~1006–1002 hPa) or significantly higher tide levels (>20 ft) combined with higher flood likelihood from NOAA. In this case, the NOAA flood likelihood is close to 0%, indicating no notable flood threat.
CATEGORY 2
WHAT
No significant flooding is anticipated, despite a somewhat lower barometric pressure overnight (~1005 hPa). Tides near 19.9 ft are forecast, but this remains well below levels previously linked to higher flood categories.
WHEN
Early morning high tide near 06:00 AM PST.
IMPACTS
Little or no coastal flooding impacts expected in low-lying or shoreline areas. Normal tidal variations are the most likely outcome.
Although the morning barometric pressure on 12/19 is lower than on Day 1, it is still not near the historically critical lows (~992 hPa). NOAA’s daily flood likelihood stands at 0.9%, which remains too small to suggest a substantial flooding event. Past Category 3 and 4 scenarios typically included more extreme conditions (tide heights above 20 ft combined with notably lower pressure or higher NOAA flood likelihood).
CATEGORY 2
WHAT
No meaningful flood risk is expected. While morning tide levels could approach 20.0 ft, the barometric pressure is forecast to be quite high (~1023 hPa), greatly reducing any potential for coastal flooding.
WHEN
Peak high tide around 06:30 AM PST.
IMPACTS
No flooding concerns. Shorelines and low-lying areas should see normal conditions without inundation.
Historically, moderate or higher flood events in Redondo Beach have occurred with lower barometric pressures, substantial wind forcing, or a substantially higher NOAA flood likelihood. The 1.2% flood likelihood from NOAA for 12/20 remains too minimal to indicate a threat. Although the tide approaches 20 ft, the very high pressure (above 1020 hPa) further lowers the chance of water levels reaching critical thresholds.
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.
