Redondo Beach, WA
CATEGORY 2
WHAT
No risk of flooding is anticipated despite relatively high tides (peaking near 19.1 ft) because the barometric pressure is significantly elevated (around 1023–1024 hPa), reducing the likelihood of any coastal inundation.
WHEN
– Highest tide around 04:54 AM and again near 14:00 PM.
IMPACTS
No expected flooding impacts. Minor water level rises along the immediate shoreline, but conditions are not expected to approach flood thresholds.
• NOAA’s Flood Likelihood is listed as 0.0% for December 17, reflecting minimal concern.
• Historical comparisons show that higher barometric pressure in the 1020+ hPa range greatly reduces flood risk at this tide level.
• Overall conditions align with a Category 2 event (no risk of flooding) given the elevated pressure and relatively modest tide height compared to known flood events.
CATEGORY 2
WHAT
No risk of flooding is expected. The early morning high tide may reach about 19.6 ft, but barometric pressure is still fairly high (roughly 1018 hPa), limiting the chance of significant coastal flood impacts.
WHEN
– Highest tide around 05:30 AM and again near 14:36 PM.
IMPACTS
No notable impacts. Water may approach typical high-tide marks but is unlikely to inundate roads or low-lying neighborhoods.
• NOAA’s Flood Likelihood remains at 0.1% for December 18.
• This tide level, though moderately high, does not coincide with the substantially low barometric pressure often seen in historical, more serious flood events.
• Conditions safely fit within Category 2 (no risk of flooding).
CATEGORY 3
WHAT
Close to a flood event and worth monitoring, but still unlikely to result in significant flood damage. Tides may exceed 19.8 ft while barometric pressure dips to around 1006–1007 hPa—lower than on the previous days.
WHEN
– Highest tide expected near 06:00 AM and again around 15:12 PM.
IMPACTS
Although widespread flooding is not expected, brief minor flooding in more vulnerable low-lying areas cannot be ruled out. A few roads or park areas adjoining the shoreline could see minor water encroachment.
• NOAA’s Flood Likelihood remains low at 0.9%, yet the combination of a higher tide and lower pressure places this day closer to flood thresholds than the preceding days.
• Historical data (e.g., Category 3 events) indicates that tides near 20 ft with moderately reduced barometric pressure can produce brief, minor coastal flooding.
• Overall, this remains a Category 3 event: close to a flood situation and worth monitoring, but unlikely to produce major impacts.
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.
Categories 1-2: No risk of flooding.
Category 3: Close to a flood event and worth monitoring.
Category 4: Flooding is likely however, it is uncertain if this will cause major property damage.
Category 5: Likely to flood and cause property damage.
Categories 6-7: Extremely high risk of flooding and property damage.
