Federal forecasters say peak of hurricane season will be busy
PENSACOLA, Florida (AP) — Record high ocean temperatures and the
development of a climate phenomenon known as La Nina will keep the
Atlantic hurricane season on track to be the busiest since 2005,
government forecasters said Thursday.
The National Oceanic and Atmospheric Administration slightly lowered
the outlook it released in May, but an above-normal season was still
expected, said Gerry Bell, lead seasonal hurricane forecaster at NOAA's
Climate Prediction Center in Washington.
The updated forecast calls for 14 to 20 named tropical storms, down
from a range of 14 to 23. The hurricane season started June 1 and ends
Nov. 30, but the peak period for hurricanes runs from August through
October.
Eight to 12 storms could become hurricanes, and four to six of those
hurricanes could become major storms, with winds of 111 mph or more,
forecasters said.
"August heralds the start of the most active phase of the Atlantic
hurricane season and with the meteorological factors in place, now is
the time for everyone living in hurricane prone areas to be prepared,"
NOAA Administrator Jane Lubchenco said in a statement.
Historically during active storm seasons, multiple hurricane strikes
are much more likely for both the Gulf Coast and the East Coast in the
U.S.
The Caribbean also sees a sharp increase in storm activity during such
seasons, which is bad news for Haiti, where approximately 1.6 million
people continue to live under tarps and tents nearly seven months after
a catastrophic earthquake wrecked its capital.
Three named storms have developed since this hurricane season began.
Hurricane Alex made landfall June 30 in northern Mexico. Tropical Storm
Bonnie forced crews drilling a relief well in the Gulf of Mexico to
evacuate last month but petered out.
Tropical Storm Colin regenerated Thursday with 45 mph winds over the
open Atlantic, said forecasters at the National Hurricane Center in
Miami. A tropical storm warning was issued for Bermuda.
The May outlook — which called for eight to 14 hurricanes, with
possibly three to seven major hurricanes — reflected the possibility of
even more storms forming in June and July than actually did, Bell said.
Bell said the update is based on conditions indicating a high-activity
era that began in 1995 continues.
"The atmospheric and oceanic conditions now in place are very conducive
to hurricane formation, as we had predicted in May," he said.
The Pacific Ocean climate phenomenon La Nina developed in July,
reducing wind shear in the Atlantic and making it easier for storms to
take shape.
Sea-surface temperatures are exceptionally high, and the warmest since
2005 when Hurricanes Katrina and Rita ripped into the same part of the
Gulf Coast now coping with one of the world's worst oil spills.
Historically, three named tropical storms will spin into the Gulf of
Mexico between August and November during above-normal seasons, Bell
said. Any impact on the oil remaining in the Gulf from an April 20 rig
explosion off Louisiana would depend on a storm's strength and path
across the water.
Tropical storms are named when sustained wind speeds reach 39 mph. They
become hurricanes when sustained winds reach 74 mph. Major hurricanes
blow at 111 mph or more. The strongest hurricanes are labeled Category
5, with winds greater than 155 mph.
Three hurricanes developed out of nine tropical storms in 2009. None of
the hurricanes made landfall in the USA. Hurricane Ida hit Nicaragua as
a Category 1 storm in November.
Colorado State University researchers said Wednesday they also expected
this year's season to be more active than average with 10 hurricanes,
five of them major.
