Redondo Beach, WA
CATEGORY 3
WHAT Minor coastal flooding expected. Possible inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.
*WHEN From 12:00 AM to 11:59 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure is forecasted to be around 1007 hPa during the high tide at 01:12, which is higher than the threshold that indicates a severe flood risk. However, the tide height is not provided in the user data, which is a critical factor in assessing flood risk. Based on historical events, a tide height over 16 Ft combined with low barometric pressure increases the likelihood of coastal flooding. The NOAA's Flood Likelihood Analysis indicates a low likelihood of flooding for this day, with a distance to threshold of -1.25m from the flood threshold of 2.1m. Wind direction is also a factor; however, without specific wind data for this day, it's challenging to assess its impact fully. Comparing with historical events, particularly the Category 3 event on 12/27/2023 with similar barometric pressure but higher tide height, the risk on this day seems lower but still warrants monitoring due to potential rainfall and existing tide levels.
CATEGORY 2
WHAT Coastal conditions expected to be relatively stable with a very low chance of flooding.
WHEN Throughout the day.
IMPACTS No significant impacts expected barring unforeseen changes in weather conditions.
On this day, the barometric pressure during high tide at 16:24 is forecasted to be around 1009 hPa, which is above the critical threshold for severe flooding risk. The NOAA's Flood Likelihood Analysis continues to indicate a low likelihood of flooding with a distance to threshold of -1.32m from the flood threshold of 2.1m. Without specific high tide height data for this day, it's difficult to make a precise assessment; however, given the pressure data and NOAA's analysis, significant flooding is not anticipated.
CATEGORY 4
WHAT Elevated risk of coastal flooding due to lower barometric pressure and potential high tide levels.
WHEN Higher risk during high tides, especially around midday.
IMPACTS Possible moderate flooding of coastal areas, roads, and properties close to the shoreline. Residents should be prepared for potential road closures and water reaching structures.
The barometric pressure on this day drops closer to concerning levels at around 1004 hPa during the early morning high tide and further down to approximately 1002 hPa by midday. These pressures are closer to those experienced during previous Category 4 events. The NOAA's Flood Likelihood Analysis still indicates a low likelihood of flooding; however, given the proximity to concerning barometric pressure levels and without specific high tide height data, there is an elevated risk compared to the previous days. Historical events suggest that such pressure levels can lead to more significant flooding if accompanied by high tides over 16 Ft and certain wind conditions.
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 adhere to any evacuation orders or safety instructions provided by emergency services.
