WHAT... The provided data for December 24, 2023, indicates lower barometric pressure than the historical Category 4 events but significantly higher tide heights. The mean pressure MSL for the high tides is above 1025 hPa, which is considerably higher than the historical thresholds associated with significant flooding. Despite the high tide levels, the much higher barometric pressures reduce the risk of flooding.
WHEN... The risk of flooding is low on this day despite the high tide because of the substantial barometric pressures. Historical data and NOAA's Flood Likelihood Analysis also indicate a low likelihood of flooding (0.2%).
The weather conditions, including cloud cover and light rain, suggest moderate weather that is not indicative of severe flood risks. Comparatively high barometric pressure during high tide times further lowers the chance of a flood event.
CATEGORY 1
WHAT... On December 25, 2023, although the barometric pressure drops to around 1015 hPa during one of the high tides, which is closer to historical Category 4 events, it's still above the critical threshold. Combined with low NOAA flood likelihood (0.8%) and a negative distance to threshold (-0.373m), flood potential remains low.
WHEN... The likelihood of flooding remains minimal due to relatively high barometric pressure and low NOAA flood likelihood prediction.
The weather forecast showing light drizzle and cloud cover does not present significant risk factors for flood conditions. The overall conditions are comparatively stable and do not warrant a high flood potential rating.
CATEGORY 3
WHAT... The barometric pressures on December 26, 2023, remain very high, exceeding 1031 hPa during both high tides, contrary to the historical Category 5 event's lower pressure threshold. However, NOAA indicates a high likelihood percent (5.6%) compared to previous days.
WHEN... Despite NOAA's higher flood likelihood rating for this day, the extraordinarily high barometric pressure significantly diminishes the risk of a flooding event.
Weather conditions with moderate rain are expected but should be mitigated by the strong barometric pressures. The wind direction from S/SSW also does not align with the W/NW that could contribute to elevated flood risks.
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 consult with local authorities or experts for up-to-date information and decision-making in flood-related situations.
