Redondo Beach, WA
CATEGORY 3
WHAT... Elevated flood potential due to high tides and low barometric pressure.
WHEN... Peak risk near the times of high tide, particularly at 11:54 AM when barometric pressure is also relatively low, though not below the critical threshold.
The mean pressure at MSL is above the critical threshold of 966 hPa which diminishes the risk of flooding to some extent. However, the combination of expected weather conditions and high tides suggests a cautious approach for potential localized flood events. The weather code indicates light rain, which could contribute additional but likely minimal runoff.
CATEGORY 4
WHAT... Increased flood potential due to very high tides and low barometric pressure nearing critical thresholds.
WHEN... Highest risk occurs near the high tide timings early in the afternoon, compounded by lower barometric pressure that is closer to the threshold observed during historical flood events.
The mean pressure at MSL is 1005.242 hPa, which is slightly lower than the previous day but still above the critical threshold. The proximity to this threshold alongside the high tide hints at a greater risk for flooding. Foggy conditions are expected, which typically would not contribute significantly to flood risks; however, with the low pressure and high tide, vigilance is advised.
CATEGORY 2
WHAT... Low to moderate flood potential with milder tides and higher barometric pressure.
WHEN... Lower risk throughout the day due to more favorable weather conditions despite high tides.
The mean pressure at MSL is higher at 1011.603 hPa, reducing concerns for flooding on this day. While tides remain high, the absence of heavy rain and stronger barometric pressure provide a more stable outlook. Historical data from December 2022 shows windier and rainier conditions leading to floods, which are not present in this forecast.
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. Always adhere to local advisories and consult with authorities for real-time assessments and guidance.
