Is c the answer?

Question

22. How soon after a hurricane makes landfall is it no longer a flooding threat?

a. After the winds drop below 74 mph

b. After the winds drop below tropical storm-force speed

c. 12 hours after landfall

d. It depends on what other weather systems it interacts with.

Answer 1

Actually it's none of them, the flood threat is over when the storm is no longer in the area, however, once that storm is cleared, another one may take its place.

Answer 2

It is difficult to say.There are two types of floods associated with a hurricane.First one is due to storm surge(abnormal rise of sea level near the coast) which depends upon the intensity of the hurricane and consequent strong winds.Sometimes the topography of the sea-bed near the point where it croses also counts.Further,elevation of the total sea level increases when peak surge occurs at the time of high tide causing severe floods.This storm surge occurs at the time of the hurricane crossing the shore and may last one or two hours after that.

Secondly,flood may be caused due to heavy and prolonged rains over inlands immediately after the crossing of the hurricane(particularly along the track of the hurricane) which will flood the rivers and low lying areas.This may sometimes continue for a few days if the hurricane does not get weakened immediately and continues as a low pressure area.

Answer 3

The Correct Answer is "D"

There are so many variables to that Question because I have seen them be a threat for as long as several days as they interact with other weather systems or how much moisture they contain. so the Answer to your question is "D"
