Redondo Beach, WA
CATEGORY 4
WHAT... High tide at 07:00 with a pressure of 1025.077 hPa and at 16:36 with a pressure of 1021.690 hPa, combined with a high likelihood of precipitation, cloud cover, and sustained wind speeds around 47 mph. The NOAA Flood Likelihood for this date is high at 8.8%, suggesting an elevated risk. The weather conditions resemble those from a Category 4 event in our historical data, with the similarity in pressure readings and higher tide levels, although the barometric pressures are higher than the historical event on 12/27/2023 which was characterized by a barometric pressure of >=1006.1 hPa.
WHEN... Given the forecasted conditions and comparing them to historical events, there is a potential for flooding similar to a Category 4 event later in the day as the tide peaks and weather conditions persist.
The weather data indicates significant precipitation and strong winds from the W/NW which can exacerbate tidal effects and push more water ashore. While the barometric pressure is not as low as in previous severe events, it's trending downwards throughout the day which suggests worsening conditions that could lead to flooding.
CATEGORY 3
WHAT... High tide at 07:30 with a pressure of 1021.503 hPa and at 17:18 with a pressure of 1025.922 hPa. The weather data shows less precipitation probability compared to Day 1, and wind speeds are slightly reduced. NOAA indicates a low flood likelihood at 3.9%, which is less than the previous day but still presents some risk given the historical thresholds.
WHEN... The risk for flooding remains, especially in the morning as the high tide coincides with lower barometric pressures, but it is less likely to cause significant property damage compared to Day 1.
The weather conditions are slightly improving from the previous day with less severe wind and precipitation forecasts. The barometric pressure is still well above critical levels seen in past flooding events, reducing the likelihood of a major flood.
CATEGORY 2
WHAT... High tide at 08:00 and at 18:06 both coinciding with a mean pressure MSL of 1027.896 hPa. The barometric pressure is relatively high and stable throughout the day which suggests milder weather conditions. NOAA's flood likelihood is low at 2.7%, indicating minimal risk for flooding.
WHEN... Flooding is unlikely on this day as both high tides occur during times of higher barometric pressure, reducing the risk even further.
The consistent high barometric pressure throughout Day 3 points to calmer weather conditions. Combined with NOAA's low flood likelihood assessment, it is unlikely that the region will experience significant flooding akin to previous events.
Residents and businesses in Redondo Beach should closely monitor weather updates and be prepared for changing conditions that could lead to flooding. It's advisable to stay informed about local emergency management plans and consult with authorities for real-time updates and advisories. Always err on the side of caution, especially during high tides or heavy rainfall events.
