CATEGORY 2
WHAT No flooding is expected.
WHEN No flood risk is present on Day 1.
IMPACTS No impacts are expected.
Step 1: Assess Barometric Pressure:
The mean barometric pressures at the times of high tides are 1023.28 hPa at 02:06 AM and 1026.97 hPa at 10:00 PM. These pressures are significantly higher than those during historical flood events, indicating stable atmospheric conditions.
Step 2: Evaluate Tide Height:
The maximum tide height on Day 1 is approximately 19.406 ft at around 07:12 AM. While this is higher than the tide height during the historical Category 3 event (17.460 ft), it is still below the 21 ft threshold associated with higher flood risk categories. The elevated tide is not coupled with low barometric pressure.
Step 3: Consider Wind Direction and Speed:
Wind speeds are moderate, with a maximum of 23 mph from the south during the day. Historical events that led to flooding had higher wind speeds and directions that exacerbated sea water pushing towards the coast. The current wind conditions are less likely to contribute to flooding.
Step 4: Integrate NOAA High Tide Flooding Likelihood:
NOAA's forecast indicates a Low flood likelihood with a 0.0% chance of flooding for Day 1. The distance to the flood threshold is -1.78m, further supporting minimal flood risk.
Step 5: Synthesize Information and Forecast Flood Category:
Considering the high barometric pressures, tide heights below critical thresholds, moderate wind conditions, and NOAA's low flood likelihood, the flood potential for Day 1 is categorized as Category 2, indicating no substantial risk of flooding.
CATEGORY 2
WHAT No flooding is expected.
WHEN No flood risk is present on Day 2.
IMPACTS No impacts are expected.
Step 1: Assess Barometric Pressure:
The mean barometric pressures at the times of high tides are 1028.10 hPa at 08:00 AM and 1031.20 hPa at 05:30 PM. These pressures are considerably higher than those recorded during past flood events, suggesting stable weather conditions.
Step 2: Evaluate Tide Height:
The maximum tide height on Day 2 is approximately 19.386 ft at around 08:00 AM. This is higher than the tide height during the Category 3 historical event but remains below the critical 21 ft level. The absence of low barometric pressure reduces the risk despite the higher tides.
Step 3: Consider Wind Direction and Speed:
Wind speeds are low, ranging from 3 to 8 mph, primarily from the southeast to northeast. These wind conditions are not conducive to increasing flood risk, unlike the higher wind speeds from flood-contributing directions in historical events.
Step 4: Integrate NOAA High Tide Flooding Likelihood:
NOAA forecasts a Low flood likelihood with a 0.0% chance for Day 2. The distance to the flood threshold is -1.77m, indicating that tides are well below levels that could cause flooding.
Step 5: Synthesize Information and Forecast Flood Category:
With high barometric pressures, tide heights below critical thresholds, minimal wind impact, and NOAA's low flood likelihood, Day 2 is assessed as having a Category 2 flood potential, signifying no substantial flood risk.
CATEGORY 2
WHAT No flooding is expected.
WHEN No flood risk is present on Day 3.
IMPACTS No impacts are expected.
Step 1: Assess Barometric Pressure:
The mean barometric pressures at the times of high tides are both 1028.57 hPa at 08:54 AM and 11:36 PM. These pressures are stable and much higher than those associated with historical flooding, indicating low atmospheric risk.
Step 2: Evaluate Tide Height:
The maximum tide height on Day 3 is approximately 19.265 ft at around 08:54 AM. This is below the 21 ft threshold and the levels seen in Category 4 and 5 historical events. High tides alone, without low barometric pressure, are less likely to cause flooding.
Step 3: Consider Wind Direction and Speed:
Wind speeds are minimal, with averages around 4 to 7 mph, predominantly from the northeast and north. These conditions are not expected to contribute to coastal flooding.
Step 4: Integrate NOAA High Tide Flooding Likelihood:
NOAA's analysis indicates a Low flood likelihood with a 0.0% chance for Day 3. The distance to the flood threshold is -1.90m, suggesting tides are significantly below concerning levels.
Step 5: Synthesize Information and Forecast Flood Category:
Given the combination of high atmospheric pressure, tide heights below critical thresholds, negligible wind impact, and NOAA's low flood likelihood, the flood potential for Day 3 is classified as Category 2, indicating no substantial risk of flooding.
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.
