Why does a day with a full moon (such as today) cause greater flooding during a storm, as is being forecast for today’s thunderstorm? What’s the shaychus?
It may have something to do with the tide — last night they said at least a foot of the water was added only cos of the tide nothing even to do with the storm.
The moon is always there. More of it being lit up doesn’t add any gravity. The reason it has an effect is that when it is full it is opposite the sun, and its pull is not countered by the sun.
