Redondo Beach, WA
CATEGORY 3
WHAT... The current barometric pressure is significantly above the historical thresholds associated with major flooding events in Redondo Beach, WA. While the NOAA High Tide Flooding Likelihood indicates a high chance of flooding at 8.4%, this likelihood percentage is in line with a Category 3 event per historical data. The tide level forecasted does not reach the heights seen in previous Category 4 or higher events, suggesting that while there is a risk of flooding, it may not lead to significant property damage.
WHEN... The high tide at 06:24 with a mean pressure of 1025.9 hPa is notably higher than the Category 3 event from 12/27/2023, which had a lower barometric pressure. A second high tide at 15:54 with a mean pressure of 1026.5 hPa maintains this trend of elevated pressure and lower flood risk.
Given the absence of extremely low barometric pressures, which would greatly enhance the risk of flooding, and taking into account the NOAA High Tide Flooding Likelihood data, it can be concluded that the flood risk for Day 1 is moderate (Category 3). However, residents should monitor forecasts and be prepared to take action if conditions worsen unexpectedly.
CATEGORY 4
WHAT... The barometric pressure on Day 2 decreases slightly compared to Day 1 but remains above critical thresholds seen in historical Category 5 events and similar to those observed in Category 4 events. This decrease in pressure, combined with high tides at both 07:00 and 16:36 and slightly increased NOAA High Tide Flooding Likelihood percentages to 8.8%, raises the flood potential slightly from Day 1.
WHEN... Tides are expected to reach their peak early in the morning and later in the afternoon, with pressures of 1024.7 hPa and 1022.5 hPa respectively, indicating a potential for flooding events on par with historical Category 4 data but without reaching the critical thresholds that would indicate catastrophic flooding.
Residents should remain vigilant as conditions are closer to those that could result in minor property damage compared to Day 1. The lower barometric pressures coupled with high tide levels could result in localized flooding similar to previous Category 4 events.
CATEGORY 2
WHAT... On Day 3, there is a significant decrease in NOAA's Flood Likelihood Percentage to only 3.9%, suggesting a much lower risk of flooding compared to the previous two days. The barometric pressure remains relatively stable from Day 2's second half, indicating persistent but not severe weather conditions.
WHEN... The high tide at 07:30 has a corresponding mean pressure MSL of 1022.5 hPa, which does not reach the critical low-pressure threshold associated with significant past flooding events. Another high tide at approximately the same pressure level late in the afternoon further suggests reduced flood risks.
The lower NOAA flood likelihood combined with stable barometric pressure points toward a reduced threat of flooding on this day; hence, the categorization is downgraded to Category 2. This suggests that while tides are still high, other conditions are not conducive to severe flooding.
Residents should continue monitoring later forecasts and remain alert for possible Flood Warnings. Those living in areas prone to flooding should stay prepared to take action should conditions change. Consulting local authorities or experts is advised for definitive guidance on flood-related decisions.
