*Information on reaching the storm surge emergency warning water level: 　 Alert Level 5 equivalent information
(Information for determining the declaring of Alert Level 5 emergencies by municipalities to ensure safety)
*TPm: Average sea level of Tokyo Bay, the reference plane for elevation (altitude above sea level)
*Tide level deviation: The difference between the observed tide level and the expected astronomical tide level.
*Astronomical tide level: The tide level that rises or falls due to the influence of celestial bodies (movements of the moon, sun, or earth).
