Redondo Beach, WA
CATEGORY 2
WHAT... Based on the provided data, December 17 shows high tides peaking at 20.516 feet at 09:00 and mean pressure MSL at 1031.4 hPa. While the tide level is moderately high, the corresponding barometric pressure is significantly above the historical threshold of <=1002 hPa noted during previous Category 4 flooding events. The likelihood of flood on this day is elevated due to the high tide but mitigated by the high barometric pressure.
WHEN... Flooding risk is increased around the times of the high tides; however, the high barometric pressure reduces the likelihood of a flood event similar to historical Category 4 occurrences.
The weather conditions with fog and low visibility in the morning hours might not significantly contribute to the flooding risk, given there's no precipitation forecasted. The very high barometric pressure provides a counteracting effect to the high tide levels, lowering the immediate risk of flooding compared to historical Category 4 events. Nonetheless, vigilance during times of high tide is advised.

WHAT... The analysis for December 18 indicates a similar pattern with a high tide level at 20.409 feet at 09:42 and a mean pressure MSL at 1038.7 hPa. Again, the tide level falls below the threshold observed during Category 4 events, and the barometric pressure is well above the historical event thresholds.
WHEN... Similarly to Day 1, there is an increase in flood potential around the times of high tides, but overall risk remains moderated by notably high atmospheric pressure.
Weather data suggests clear skies with no significant precipitation contributing to flood risk. The barometric pressure is expected to rise slightly from Day 1, further reducing flooding concern. As on Day 1, standard precautionary measures are still advisable due to high tide levels.
CATEGORY 2
WHAT... On December 19, another set of moderately high tides occurs at 20.469 feet at 10:24 with a mean pressure MSL of approximately 1038.0 hPa. Similar to the previous two days, these conditions indicate an increased risk during high tide times but are less critical due to high barometric pressure.
WHEN... Elevated tides in combination with continued high barometric pressure suggest a repeated pattern of moderate flood potential that does not quite reach Category 4 criteria from historical events.
As with previous days, clear skies with no rain reduce immediate risks, and no significant changes in weather patterns are anticipated that would elevate concerns beyond moderate levels. Consistent weather conditions suggest a stable trend in flood potential throughout the three-day period.
Residents and authorities should monitor forecasts while remaining alert for possible Flood Warnings. Despite lower categorization based on available data, those living near tidal areas should remain prepared for water level fluctuations associated with tidal changes. Always consult local authorities or experts for final decisions regarding safety measures and potential evacuation orders during tidal events that may cause flooding.
