super Storm

By: tornadocam, 4:43 PM GMT on October 30, 2012

Sandy is going to be a storm in the history books. while we do not know the exact damage of the storm reports are coming in it is going to be a billion dollar disaster. Second Sandy did something very unusual and that is merged with a strong cold front to create a super storm.

Sandy was an intense storm based on pressure readings 940 milibars that is typical of a category 4 hurricane. Sandy at its peak was a very strong category 2 hurricane. The storm made landfall in south New Jersey as a category 1 90 mph hurricane. Now the hurricane part of of the storm striking the North East is nothing new as while it is not as common as the southern coast the North East has had a history of hurricanes, what was rare was the intensity and the super storm

As sandy was coming on shore it was starting to look like a very strong Northeaster type storm. Behind the warm side of the storm there was heavy snowfall and very arctic air. The storm also produced heavy rainfall and very high storm surge. So it was in a way a hybrid of a Northeaster and a Hurricane. So how common is this

As I stated Hurricanes impact the Northeast so that is not to unusual. But how common is a hybrid storm. Well the Last thing similar to Sandy was the 1991 Perfect storm. The 1991 perfect storm had been a hurricane in its past life but it made the transition to a strong Northeaster. The storm brought heavy rain, winds over 70 mph and a storm surge to New England that is the closest thing in comparison to Sandy.

However unlike the 1991 storm. Sandy was mostly tropical when it made landfall in New Jersey then it became a powerful Northeaster type storm after merging with a cold front. The storm that Sandy is being compared to it is the 1938 New England Hurricane. The 1938 New England Storm came on shore at a similar intensity as Sandy based on pressure. This storm brought storm surge over 10 feet and high winds to New York, and New England.

No doubt, Sandy will go down in the record books as one of the more intense storms of any kind to strike the North East. Due to it merging and creating a Northeaster It belongs in its own category. Here is a list of Hurricanes to strike the North East. 1938 New England storm, 1954 Carol and Edna, 1960 Donna, 1985 Gloria, 1991 Bob, 2011 Irene and now Sandy.

Northeast Not immune to Hurricanes

By: tornadocam, 5:18 PM GMT on October 25, 2012

The northeast Region of the United states could be next week be hit with a hurricane. Usually it is the Gulf or southeast Coast that gets the most attention. Most hurricanes that strike the USA either hit the Gulf of Mexico or the Carolina's and sometimes Virginia. But the Northeast has had its share of tropical storms. Sadly despite this there is a myth and belief that hurricanes cannot hit the Northeastern USA (New York and New England). I will take a look back at some tropical storms that have struck the North East

1938- A large and powerful Category 3 hurricane made landfall In New York and Connecticut this hurricane did a lot of damage.

1954-Hurricane Carol impacted New England as a category two hurricane. Carol claimed 68 lives and damage was at $460 million (1954 dollars)

1954-Hurricane Edna a category 1 hurricane at landfall that also impacted New England. Edna claimed 29 lives and $40 million in damage

1960-Donna, Donna had impacted Florida as a category 4 and North Carolina as a category 2. Donna also made landfall in New England as a category 2. Overall Donna claimed over 300 lives and cost $900 million

1985-Gloria made landfall in New England as a strong category 2 hurricane. Gloria cost $1 billion in damage and 8 lives

1991-Bob made landfall in New England as a category 2 costing $1.5 Billion in damage

2011-Irene, Irene had devastated North Carolina & Virginia as a Category 1 hurricane, but it also made landfall in New Jersey as a category 1 and New York as a Tropical Storm. Irene caused damage up to $14 Billion and over 50 people perished

so the North East is not immune to Hurricanes and has had its share of bad Hurricanes maybe not like the southern coast but still their have been bad ones.

if you live on the coast you should always be prepared

Active Hurricane Season

By: tornadocam, 7:27 PM GMT on October 24, 2012

For the third year in a row the Atlantic hurricane season has been above average. So far in 2012 we have had 19 named storms.We also saw 19 storms named in 2010 and 2011. Keep in mind in an average year the Atlantic basin sees 10 named storms, 6 become hurricanes and 2 become major hurricanes (category 3 or higher). So why so many tropical storms. The answer is strongly linked into the La Nina and El Nino affect. I will explain each scenario.

La Nina conditions is when waters in the tropical Pacific cool but the Atlantic water temps rise. Also in La Nina shearing winds, which suppress tropical storms from forming, are relaxed. This increases more tropical storms in the Atlantic basin. Recent examples of La Nina's 2004 (15 storms) 2005 (28 storms), 2010 (19 storms) and 2011 (19 storms)

Neutral conditions is when La Nina or El Nino are not present. Temperatures in the tropical pacific may be average are above. The Atlantic water temps may be average or above average. Shearing winds are present but they are typical. So due to the warm waters Neutral conditions also favor above average tropical storm activity in the Atlantic. Examples of Neutral years 2001 (15 storms) 2002 (12 storms), 2003 (16 storms) 2007 (15 storms) 2012 (current season so far 19 storms have formed)

El Nino, During El Nino years the tropical Pacific water temps warm while the Atlantic has cooler water temps sometimes. During El Nino years shearing winds are increased thus tropical storm activity in the Atlantic is greatly reduced and is often below average. For example in 2009 a very strong EL Nino was active and greatly reduced tropical storm activity. During the 2009 season only 9 named storms formed and most were short lived.

So far in 2012 we have been in a Neutral state. Water temperatures have been running above average. The systems so far in 2012 have been short lived but there have been a lot of storms. The reason for some of the storms being short is unlike the past two years there has been some shearing winds that are typical. This has kept a lot of the storms in check as so far only one storm has become a major storm.

we have till November the 30th to go so more storms can form. The bulk of the activity has occurred in the most active part of the season. August, September and October are the most active months in Hurricane season. However, if conditions are right November can be active and their have been late season storms in November some have been destructive
