Redondo Beach, WA
CATEGORY 2
WHAT... The weather data indicates overcast conditions with light drizzle and an average temperature around 48°F. The barometric pressure is high, peaking at 1016 hPa during the current condition, which is significantly higher than the threshold that typically indicates a higher risk of flooding (992.8 hPa). The high tide level is expected to reach a maximum of approximately 20.206 feet at 08:00 AM, which is below the historical flood event thresholds and also corresponded with very high pressure, suggesting low flood risk. Wind direction from SSE will have some impact but is not expected to significantly increase flood risks.
WHEN... Given the high barometric pressure and relatively moderate high tide levels compared to historical flooding events in Redondo Beach, WA, there is a low risk of flooding on this day.
Despite the high tide, the barometric pressure's deviation from historical flood-inducing levels greatly reduces the likelihood of a flooding event. NOAA's predicted low flood likelihood for this date (2.7%) aligns with the assessment, confirming minimal risk. However, ongoing monitoring of weather conditions is recommended due to the possibility of unforeseen changes.

WHAT... On this day, there will be clear skies and sunny weather, which usually diminishes the chances of flooding. The barometric pressure remains high at around 1020 hPa throughout most of the day but shows a significant drop to approximately 1023 hPa by midnight, aligning with a high tide event. The high tide level at 08:30 AM will be approximately 20.067 feet but grows to notably higher levels in the evening closer to historical flood event thresholds.
WHEN... Although most of the day has weather conditions unfavorable to flooding, the combined effect of dropping barometric pressure towards late evening and increasing tide levels warrants caution for potential minor flooding events, particularly when comparing to historical Category 3 events.
The NOAA forecast reports a very low likelihood of flooding (1.0%), but with barometric pressure slightly decreasing while approaching a nighttime high tide, vigilance is suggested during late hours. It's crucial to monitor real-time tide levels as they approach peak heights that may prompt localised flooding situations.

WHAT... The new year starts with partially cloudy skies transitioning into overcast conditions by afternoon. The barometric pressure drops further throughout the day, reaching approximately 1017 hPa by late evening. This is closer to historical flooding events’ pressure thresholds, heightening concerns especially since it coincides with an evening high tide projected around 19.883 feet.
WHEN... The risk for flooding increases during late evening due to a combination of lowering barometric pressure and rising tide levels. Although NOAA's likelihood percentage is extremely low (0.3%), physical conditions are more conducive to flooding on this date than on previous days.
While the pressure suggests some increased risk when compared with previous days' data, it remains much higher than the critical threshold seen in past severe floods in Redondo Beach. Therefore, despite some risk factors aligning by evening, substantial flooding remains unlikely but should be watched closely.
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 refer to local authorities for emergency procedures and for more comprehensive information regarding flood risks in your area.
