Redondo Beach, WA
CATEGORY 3
WHAT... Analysis of Day 1's weather and tidal data indicates that the conditions for flooding are moderate. None of the high tides for the day are above or close to the historical flood event benchmarks; however, the barometric pressure values are significantly higher than those observed during past flood events.
WHEN... The highest tides on this day are at 09:42 and 20:36, with corresponding mean pressures well above the threshold that would typically indicate flood risks.
Despite high tides not reaching critical levels that historically led to flooding, precautions should still be taken due to regional susceptibility to such events. The tide levels for this day peak significantly lower than the historical flooding benchmarks, and barometric pressures are above 1030 hPa, which considerably lessens the risk of flooding.
CATEGORY 2
WHAT... Comparative analysis for Day 2 using similar parameters as Day 1 suggests a reduced potential for flooding. High tide levels remain below historical flood event benchmarks, and barometric pressure is high, which typically indicates stable atmospheric conditions and a lower risk of flooding.
WHEN... With high tides predicted for 10:24 and 22:12 and associated pressures remaining well above the threshold indicative of flooding, the risk on this day is considered low.
Although there is consistent precipitation forecasted, with cloud cover indicating overcast weather potentially leading to rain, the exceedingly high barometric pressure readings counteract what would otherwise be contributory factors to increased flood risk. The data shows a continuous trend of high pressures and tide levels that do not approach historical flood-inducing levels.
CATEGORY 3
WHAT... Focused analysis on Day 3's conditions in comparison to historical data and Boeing Field's December observations suggests a slightly elevated risk compared to Day 2. Tide heights remain below critical levels, but barometric pressure decreases to around the lower range of the typical spectrum—though still not as low as historical event benchmarks.
WHEN... A high tide at 11:06 with a mean pressure MSL reading closer to the threshold requires closer monitoring. Historical data indicates that flooding risks increase as pressures approach 1000 hPa.
The likelihood of daily flood events provided by NOAA CO-OPS for Seattle indicates a high likelihood percentage ranging from 5.6% to 7.1% across these days, suggesting that while outright floods are not highly probable, concerned residents should remain vigilant. It should be noted that while NOAA's predictions indicate a high likelihood in their categories, this does not necessarily equate to a certainty of flooding but rather an increased risk relative to other periods.
Residents 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. Consult local authorities or experts for final decision-making in flood-related situations and stay informed about weather conditions as they evolve.
