The National Oceanic and Atmospheric Administration (NOAA) released its predictions for the upcoming hurricane season that begins on June 1 with expectations that the north Atlantic region will be "very active" in terms of tropical storm events. This news comes on the heels of the record breaking 2005 tropical season that saw 28 storms and many powerful hurricanes that decimated the Gulf Coast. NOAA continues to focus on preparedness as the best way to limit the impacts of these storms and the real threat exists that the mid-Atlantic and northeast may see a significant storm this year. JB

NOAA today announced to America and its neighbors throughout the north Atlantic region that a very active hurricane season is looming, and encouraged individuals to make preparations to better protect their lives and livelihoods. May 21-27 is National Hurricane Preparedness Week.
During a news conference at the NOAA National Hurricane Center, Deputy Secretary of Commerce David A. Sampson noted, "Preparation is the key message that President Bush wants to convey during National Hurricane Preparedness Week. The impact from these storms extends well beyond coastal areas so it is vital that residents in hurricane prone areas get ready in advance of the hurricane season."
"For the 2006 north Atlantic hurricane season, NOAA is predicting 13 to 16 named storms, with eight to 10 becoming hurricanes, of which four to six could become 'major' hurricanes of Category 3 strength or higher," added retired Navy Vice Adm. Conrad C. Lautenbacher, Ph.D., undersecretary of commerce for oceans and atmosphere and NOAA administrator.
On average, the north Atlantic hurricane season produces 11 named storms, with six becoming hurricanes, including two major hurricanes. In 2005, the Atlantic hurricane season contained a record 28 storms, including 15 hurricanes. Seven of these hurricanes were considered "major," of which a record four hit the United States. "Although NOAA is not forecasting a repeat of last year's season, the potential for hurricanes striking the U.S. is high," added Lautenbacher.
Warmer ocean water combined with lower wind shear, weaker easterly trade winds, and a more favorable wind pattern in the mid-levels of the atmosphere are the factors that collectively will favor the development of storms in greater numbers and to greater intensity. Warm water is the energy source for storms while favorable wind patterns limit the wind shear that can tear apart a storm's building cloud structure.
This confluence of conditions in the ocean and atmosphere is strongly related to a climate pattern known as the multi-decadal signal, which has been in place since 1995. Since then, nine of the last 11 hurricane seasons have been above normal, with only two below-normal seasons during the El Nino years of 1997 and 2002.
