Tropical Storm Sandy became a hurricane in the same way as any other. The storm drew in moist air that was present due to warm ocean water. This moist air provided energy that strengthened the convection within the storm, causing the pressure to drop and pull air in with even grater force, which increased wind speeds. When those speeds reached 74 mph Sandy became a hurricane.

What is the mileage of a tropical storm to turn into a hurricane?

A tropical storm becomes a hurricane when sustained winds reach 74 mph or more.


When is a hurricane considered a tropical storm and what are all the different types a storm a hurricane can turn into?

A hurricane cannot be a tropical storm as by definition a tropical storm is weaker than a hurricane. A tropical storm is a tropical cyclone with winds of 39-73 mph. Only when winds reach 74 mph or greater is the storm considered a hurricane. A hurricane can weaken into a tropical storm and from there into a tropical depression (winds under 39 mph). A tropical storm or depression may also degenerate into a remnant low, which is too disorganized to be considered a tropical cyclone. A tropical cyclone (hurricane, tropical storm, or tropical depression) may also become an extratropical cyclone after moving over land or cold water. Around the world hurricanes have different names. In the northwest Pacific ocean they are called typhoons, In the Indian ocean they are called intense tropical cyclones, and in the south Pacific they are simply called cyclones. However, these are just different names for essentially the same kind of storm.


Tropical storm Isacc?

Tropical Storm Isaac was a relatively weak tropical storm that formed during the 2018 Atlantic hurricane season. It affected parts of the Caribbean, including the Lesser Antilles and Puerto Rico, before dissipating without causing significant damage.


Why is Hurricane Sandy called Hurricane Sandy?

The National Hurricane Center, based in Miami, Florida, assigns names to tropical storms originating in the North Atlantic based upon a pre-determined list. So this one was just Sandy's turn. Identified as a tropical wave in the western Caribbean Sea on October 22, it gained intensity to the level of a tropical depression, then quickly became a tropical storm. Slowly moving northward toward the Greater Antilles, she gathered her strength and became a hurricane just before making landfall at Jamaica.See more information at the relatedlink(s) listed below:


Why was it unusual for Hurricane Sandy take the course it took?

It is unusual for a hurricane to turn make a westward turn towards the U.S. east coast. Most hurricanes that occur in that region will tend to make and eastward turn out to sea. Sandy also intensified do to interaction with and extratropical storm system in a manner not seen since the Perfect Storm of 1991.

How is hurricane sandy different from other hurricanes?

There are a few ways. First of all, Hurricane Sandy ended up combining with another storm system in a manner similar to the Perfect Storm of 1991. This resulted in an abnormally large cyclone with gale force winds covering an area 1,100 miles across. Sandy had transitioned into an post-tropical cyclone and so technically was not a hurricane at landfall, though it was just as strong as one. Hurricanes impacting the U.S. east coast will either continue moving north or turn east and head out to sea. Hurricane Sandy was unpecedented in that it turned west, slamming directly into the East Coast.


Why were people not prepared for Hurricane Sandy?

There were a few reasons. First, Hurricane Sandy made a direct impact on a region not accustomed to storms of that magnitude. Second, Sandy was a very unusual storm in a number of ways, including its unprecedented westward turn. Third, that same region had been impacted by Hurricane Irene the previous year. Irene was a damaging storm, but was not quite as bad in the northeast region as had been expected. As a result, many dismissed the dire warnings about Hurricane Sandy as exaggeration.


Why was Hurricane Sandy considered a perfect storm?

Hurricane Sandy behaved in a similar manner to the Perfect Storm of 1991 in how it combined with an extratropical storm system and gained strength. Although Sandy was only a Category 1 hurricane when it made landfall on Atlantic City, NJ on Monday, October 29, 2012, other factors combined to make it a "perfect storm." Hurricane Sandy came from a merging of several things; a storm beginning in the warmed waters of the ocean, a funneling of cold air from the Arctic that pushed it onto the coast, and a high tide that coincided with the storm swell. Other factors that made Sandy a unique storm: its extremely low pressure (946 millibars on landfall), it's size (almost 1,000 miles wide), and it's path (making a sharp left turn into the Jersey shore, powered by high pressure from a system in Canada).


What was the path of Hurricane Sandy?

Hurricane Sandy formed as Tropical Depression Eighteen over the eastern Caribbean Sea on October 22, 2012. The system traveled northward, becoming a hurricane and striking Jamaica on October 24, and Cuba on October 25 as a strong category 2 hurricane. Sandy then weakened to a category 1 hurricane over the Bahamas on October 26 and traveled parallel to the U.S. east coast. Then on October 19 Sandy made a westward turn and struck New Jersey as an extratropical cyclone. Sandy weakened and continued inland over Pennsylvania, degenerating into a remnant low.


Why was Hurricane Sandy so unusual?

Hurricane Sandy was unusual in a few ways. It started of as a fairly ordinate hurricane, but later merged with a mid-latitude storm system, which caused to the become a rather powerful storm system similar to the Perfect Storm of 1991. Second, it was extremely large, at over 1,100 miles across. Third, it made an unprecedented westward turn to hit the East Coast. Other East Coast hurricanes have either kept moving on a northward path or turned eastward out to sea.
