Flood Watch

Redondo Beach, WA

Day 1: 2023-12-27

CATEGORY 3

WHAT... The barometric pressure is forecasted to be significantly higher than the threshold observed during previous severe flood events. This is an indication of less severe weather conditions. While there is 100% chance of rain, which could contribute to increased flood risks, the lack of significant precipitation depth (0.0 inches reported) and moderate wind speeds suggest a reduced likelihood of severe flooding. The high tide level, although substantial, does not reach the heights observed during past Category 4 or 5 events. NOAA's Flood Likelihood Analysis points to a high likelihood of a flood event, but with a relatively low percentage compared to historical Category 5 events.

WHEN... Flooding risks are present due to high tides combined with the expected weather conditions; however, the elevated barometric pressure should mitigate the potential severity. The high tide at 06:24 with Mean Pressure MSL at 1025.9 hPa suggests that while water levels are high, the pressure system is more stable than during historical extreme flooding.

ADDITIONAL DETAILS...

The wind direction from the north is not indicative of severe storm conditions that often contribute to flooding in coastal areas. With this in mind, along with the NOAA prediction for a high likelihood but low percentage of flooding, it is advised to monitor the situation closely as conditions are somewhat similar to a Category 3 event from historical data.

Day 2: 2023-12-28

CATEGORY 3

WHAT... Similar to Day 1, the barometric pressure remains high, indicating stable weather patterns and a lower risk of severe flooding. The expected tide levels for Day 2 are also below those seen during Category 4 and Category 5 events. While NOAA's analysis indicates a high likelihood of flooding, it's important to note that the percentage is slightly higher than Day 1, yet still below thresholds observed during more significant flood events.

WHEN... The most critical period will be around the high tide at 07:00 with Mean Pressure MSL at 1025.4 hPa and again at 16:36 with Mean Pressure MSL at 1024.0 hPa. These pressure readings are relatively high and should not exacerbate flood conditions despite coinciding with peak tide times.

ADDITIONAL DETAILS...

The weather forecast predicts rainfall which may contribute to localized accumulation of water; however, without data on precipitation depth, it is difficult to predict the impact precisely. It's recommended that residents stay informed about rainfall intensity as it might increase flood risks in conjunction with high tides.

Day 3: 2023-12-29

CATEGORY 2

WHAT... A slight decrease in barometric pressure compared to the previous days suggests slightly more active weather conditions, yet still above thresholds associated with historical severe flood events. The NOAA Flood Likelihood Analysis for this day indicates a low risk of flooding and shows an even further reduction in percentage likelihood compared to Days 1 and 2.

WHEN... The time to watch would be during the predicted high tides at 07:30 and 17:18 with Mean Pressure MSL at 1023.6 hPa for both times. Although these are the days' peak tide levels, they remain below any major historic flood event thresholds.

ADDITIONAL DETAILS...

Given both the lower NOAA likelihood percentage and stable barometric pressure readings closer to those seen in non-flooding weather patterns, Day 3 presents lower flood risks overall. However, vigilance is recommended as local rainfall can still affect immediate coastal areas.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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. Consultation with local authorities or experts is essential for final decision-making regarding safety measures and potential evacuation procedures.

Residents should remain vigilant and follow updates from local meteorological services and emergency management officials. Weather conditions can change rapidly and may differ from anticipated forecasts; therefore, staying informed on current developments is critical for safety.
