Question

During what phase of the lunar cycle would there be a tropical storm which often causes storm surge that is most dangerous to coastal communities?

Answer 1

During a new or full moon

Explanation:

This is because, during these lunar phases, there is a spring tide – during high tides. Therefore because the ocean water-levels are high, storm surges push more water towards the coast leading to more destruction. Remember a storm surge is the pushing of water towards the coastline by strong cyclonic winds. A combination of astronomical tide and a storm surge is called a storm tide and is the most destructive.
