T. D. Nine in The Atlantic to become Tropical Storm Isaac, while southeast U.S. Keeps a Watchful Eye

By Ryan Matthew Dernick

According to the National Hurricane Center Tropical Depression Nine formed earlier today in the Atlantic, it is currently about 700 miles east of the

Leeward Islands. Environmental conditions are favorable for intensification and the depression is forecast to become a hurricane by Thursday. Tropical storm warnings are in now effect for the Lesser Antilles and watches have been posted for Puerto Rico and the U.S. Virgin Islands.

NOAA forecasters earlier this month increased the number of storms forecast and say they expect a total of 12 to 17 tropical storms, with as many as five to eight hurricanes, for the 2012 Atlantic Hurricane Season from June 1 to Nov. 30. Two to three of storms could become major hurricanes. It was only back in May when forecasters had initially only predicted nine to 15 tropical storms, with as many as four to eight hurricanes

So far this year there have been five tropical storms and three hurricanes with the most recent being Hurricane Gordon that just days ago passed through the Southern Azores. Since then it has become extra tropical as its remnants move ENE though Portugal.

With not one major hurricane to date yet for this Atlantic Hurricane Season

T.D. Nines Projected Path Shows that core of the storm will move westward through the Lesser Antilles while staying just South of Puerto Rico. As it continues to traverse west along the south coast of the Dominican Republic and Hati it will begin to feel the tug northward by the Deepening Trough across the Eastern United States. In response to that strengthening trough the High Pressure Ridge over Florida and Bahamas will weaken turning then Hurricane Isaac Northwest through Central Cuba.

this storm may change that.

South Florida residents and visitors in particular need to remain vigilant on updates According to The National Weather Service forecast Office in Miami, Florida. Weather Models are continuing to indicate it is becoming more likely that South Florida may be directly impacted late this weekend into early next week by this developing tropical cyclone.

Make sure to monitor the latest tropical weather forecasts or news and be prepared before the storm is at your door. Have a Hurricane Preparedness plan in place for you and your family.

North Atlantic 2012 Hurricane Season Staying Active. All Eyes on Gulf of Mexico

By: Ryan Matthew Dernick

Not since weather records began in 1851 has a tropical storm ever formed that far north in the Atlantic this early in the hurricane season this past Tuesday, according to the National Hurricane Center . When Chris took shape, it also marked the third earliest formation of the third tropical storm in the Atlantic Basin. During the years of 1887 and 1959 has such development occurred previously.  Tropical storm Chris defied

the lack of warm water and further strengthened on Thursday to a Category 1 hurricane with winds of 75mph before weakening back down to a tropical storm. Tropical storms like Chris have developed north of a latitude of 40.0 degrees, but not until August or later when the northern Atlantic waters were suitably warm enough to support such development.

As of 11 am EDT Friday Chris has become a post tropical cyclone or no longer is deemed to have tropical characteristics. Chris was located 335 miles ESE of Cape Race Newfoundland, moving WSW at 16mph with a minimum central pressure of 990mb or 29.23in. Gale force winds extend outward up to 205 miles from the center. The forecast path of Post Tropical Cyclone Chris is to begin to turn toward the South and at a slower rate of speed.

If that wasn’t enough, as I discussed two weeks ago on the tropical weather post “2012 Atlantic Hurricane Season Gets a Head Start So Should You”, that the latter half of June we would see a tropical system take shape near the Yucatan Peninsula. Low and behold the dynamical models were spot on as we now have a large low pressure off the northern Yucatan coast in the Gulf of Mexico. Its associated disturbed weather is affecting the Yucatan, Northwest Caribbean Sea, South East Gulf of Mexico including Western Cuba and South Florida . This disturbance is now poised to become the fourth named storm of the 2012 Atlantic Hurricane Season.

All residents along the entire Gulf Coast of the United States are urged by the National Hurricane Center in Miami, Florida to monitor this evolving weather system.  Forecasters at the N.H.C. give the low pressure area a 70% chance of becoming a tropical depression over the next day or so, as it slowly crawls north. The current movement is toward the northeast at 2mph with maximum sustained winds at 30mph. Models hint that this low will either move northeast toward the west central Gulf Coast of Florida or westward towards the Texas coast. At this time it is too early to tell the ultimate track, or strength with 100% accuracy. The fourth storm of the Atlantic Hurricane Season has not historically occurred in any previous season before July, since recording began 161 years ago. There is always a first time for everything and this season so far is anything but average.

2012 Atlantic Hurricane Season Gets a Head Start So Should You

By: Ryan Matthew Dernick

June 1st through November 30th is the official beginning of the 2012 Atlantic Hurricane Season. This season has no inclination to adhere to climatology as it began back in May 19 with Tropical Storm Alberto forming that Saturday afternoon off the South Carolina coast. Not since 1908 has there been a storm that early before the season officially began on June 1st .There after we dealt with Tropical Storm Beryl that marked the third time on record, that two tropical cyclones reached tropical storm strength during May before the beginning of Atlantic Hurricane Season.

The Saffir-Simpson Scale shown below is a categorization of tropical cyclones based on their wind speeds, barometric pressures and storm surges in feet. This helps forecasters inform the public in a warned area of the level of the tropical weather threat. Keep in mind even a weak tropical system can unleash tremendous amounts of rain leading to loss of life or damage to property. If a Tropical Storm or Hurricane Watch is issued that means that inclement conditions are expected in the watch are within 48 hours. If a Tropical Storm or Hurricane Warning is issued that implies that preparations should rushed to completion as adverse weather conditions are anticipated within 24 hours or less.

The National Oceanic and Atmospheric Association Forecast calls for  70 percent chance of nine to 15 named storms (with top winds of 39 mph or higher), of which four to eight will strengthen to a hurricane (with top winds of 74 mph or higher) and of those one to three will become major hurricanes (with top winds of 111 mph or higher, ranking Category 3, 4 or 5). Based on the period 1981-2010, an average season produces 12 named storms with six hurricanes, including three major hurricanes.

As far as early Tropical Atlantic Cyclones go, Tropical Storm Beryl was the most intense preseason storm to impact the U.S. directly on record. Beryl began as a fledgling low pressure system near the coast of South East Florida, off of Miami on May 23,2012. At Miami Beach there were wind gusts reported to near gale force (39-54mph) as it moved Northeast. On May 26,2012 as the system continued to move Northeast along the S.E. United States coastline it was classified as Subtropical Storm Beryl.

While Beryl continued to crawl off of the Carolina-Georgia-North Florida coast it began to enter a more hospitable environment conducive to further development with warmer sea surface temperatures and less wind shear aloft. Vertical wind shear has an inhibiting effect on tropical cyclones as it tends to dislocate the thunderstorms from the low level center blowing them off and not allowing the storm to organize or deepen further.

At 11pm EDT on May 27, 2012 Beryl transitioned from a subtropical system to a fully tropical system only 120 miles off of the North Florida Coast. On Sunday May 28 strong tropical storm Beryl came ashore near Jacksonville Beach, Florida with peak sustained winds at the time of landfall of 70mph. There was a peak wind gust recorded that evening at 73 mph in the northern part of Jacksonville Beach in Mayport.

With both Alberto and Beryl forming close to the Southeast coastline of the United States it portends that many of the systems of the 2012 Atlantic Hurricane Season will form similarly. The areas to watch for a direct impact this year will be in the Caribbean to Florida into the Northern Gulf Coast. The next name on the 2012 Atlantic Hurricane List is Chris which weather models are hinting may come out of the disturbed weather in the Northwest Caribbean and the Gulf of Mexico over the next two weeks.
