Redondo Beach, WA
CATEGORY 2
WHAT... The barometric pressure readings for the high tides of December 14, 2023, are significantly higher than the threshold associated with historical flooding events. High tide levels are not provided; however, given the pressure readings (1043.1710205078125 hPa and 1042.1287841796875 hPa), these are well above the known thresholds that have led to past flood events. Although NOAA's Flood Likelihood Analysis indicates a "High" likelihood, the percentages are relatively low, and the distance to threshold is negative, suggesting tides are below flood levels.
WHEN... Given the high-pressure system, there is a decreased risk of flooding despite NOAA's high likelihood indication on this day. The absence of wind direction data and tide height specifics necessitates caution in this assessment.
The barometric pressure is a critical factor in flood analysis. The significantly high-pressure readings far exceed the historical event thresholds for flooding, indicating that despite NOAA's prediction of a high likelihood of flooding, the actual conditions may not lead to such an occurrence on this day. The discrepancy between NOAA's likelihood percentage and the observed weather conditions emphasizes the need for cautious interpretation.
CATEGORY 2
WHAT... Continuing with above-average barometric pressures (1035.183837890625 hPa and 1033.0 hPa), the risk for flooding remains lower than what was witnessed during historical flood events. The negative distance to threshold implies tides remain below flood stage, corroborating with a lesser flood potential despite NOAA's slightly higher likelihood percentage for this day.
WHEN... Although NOAA cites a high likelihood with an increase in percentage compared to December 14, the pressure data suggest otherwise. The forecast does not reach thresholds akin to previous Category 4 or higher events.
The overall weather conditions point towards a stable atmosphere less conducive to coastal flooding. High-pressure systems typically suppress extreme weather formations that could contribute to flooding incidents such as heavy rainfall or storm surges.
CATEGORY 3
WHAT... The barometric pressure on the third day shows a decrease (1027.9451904296875 hPa and 1029.7967529296875 hPa) that starts to approach the lower thresholds associated with previous flooding events but still remains above those critical levels. NOAA's Flood Likelihood Analysis indicates an elevated percentage of flooding likelihood compared to prior days.
WHEN... The risk assessment for December 16 suggests a slight increase in flood potential due to lowered barometric pressure readings nearing historic flood event thresholds. However, without detailed tide height data and in the absence of critical wind information, this assessment will remain conservative.
Decreasing pressure could indicate a weather system moving in that may elevate flood risks slightly as compared to previous days. This data should be closely monitored for any significant changes that could affect flood potentials, particularly if pressure continues to drop and wind directions turn unfavorable.
Residents and authorities in Redondo Beach should monitor updates from local meteorological services and NOAA for changes in weather and tidal conditions. While current forecasts do not indicate severe flood risks, conditions can change rapidly. It is advisable to review safety plans and stay informed about local weather advisories or evacuation orders if they become necessary. Always err on the side of caution and refer to local experts for detailed guidance on preparedness measures.
