Redondo Beach, WA
CATEGORY 2
WHAT Minor coastal flooding expected due to high tides, but current barometric pressure suggests less severe weather conditions. Possible inundation of low-lying areas near shorelines.
*WHEN From 01:42 AM to 09:42 AM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure is significantly higher than the threshold that indicates severe weather conditions and potential flooding. The high tide at 01:42 AM has a corresponding pressure of 1013.010009765625 hPa, which is above the critical threshold of 992.8 hPa. This suggests that while the tide is high, the risk of significant flooding is reduced due to the stabilizing effect of higher atmospheric pressure. The NOAA Flood Likelihood Analysis indicates a low likelihood of flooding for this day, with a flood threshold distance of -2.6m, which supports the forecast of a Category 2 event.
CATEGORY 3
WHAT Elevated risk of coastal flooding due to high tides and slightly lower barometric pressure. Potential for water encroachment in susceptible coastal areas.
WHEN From 02:06 AM to 04:00 PM PST.
IMPACTS Increased risk of flooding in low-lying coastal areas and roads. Some property damage possible if water levels rise unexpectedly.
The barometric pressure for the high tide at 02:06 AM is 1012.6300048828125 hPa, which is closer to the historical flooding event thresholds but still above critical levels. The second high tide at 04:00 PM has a mean pressure MSL of 1011.22998046875 hPa, indicating a slightly increased risk compared to Day 1. The NOAA Flood Likelihood Analysis maintains a low likelihood rating for this day, which tempers the potential flood category to a Category 3 event.
CATEGORY 5
WHAT High risk of significant coastal flooding due to very high tides combined with low barometric pressure. Expect property damage and take necessary precautions.
WHEN From 02:30 AM to 04:48 PM PST.
IMPACTS Significant flooding likely in coastal and low-lying areas with potential for property damage and road closures. Immediate action may be required to protect life and property.
On this day, the barometric pressure drops significantly below the critical threshold with readings of 1004.6699829101562 hPa at the morning high tide and an even lower pressure of 1001.2000122070312 hPa at the afternoon high tide. These conditions are similar to those observed during historical Category 5 events, indicating a high likelihood of severe flooding impacts due to synergistic effects of very high tides and low atmospheric pressure.
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. Consult local authorities or experts for final decision-making in flood-related situations and adhere to any evacuation orders or safety instructions provided by emergency services.
