TROPICAL STORM KARL BECOMES HURRICANE OVER GULF 17 September 2010 From space the three storms, currently all hurricanes, are clearly visible
Tropical Storm Karl has been upgraded to a hurricane having gathered strength as it
passes over the Gulf of Mexico.
The US National Hurricane Center (NHC) upgraded Karl to a category one hurricane
and a few hours later to a category two.
Before moving into the Gulf, Karl made landfall in Mexico's Yucatan Peninsula, where it
downed trees and cut power.
Out in the Atlantic two more hurricanes are churning, including a powerful category four
storm, Hurricane Igor.
On Wednesday, both Igor and Hurricane Julia were classified as category four storms,
the first time in a decade that two simultaneous Category Four storms have been seen.
However, according to the NHC Hurricane Julia has weakened to a category one storm
on the scale of one to five and is currently pushing sustained winds of 128 km / h (80mph).
Life-threatening swells
Igor's top wind speed has increased to 230 km / h — making it the most powerful
hurricane of the season.
The NHC describes Igor as “large and powerful” and while the hurricane is not
expected to make landfall for days, forecasters say that Puerto Rico, the Virgin Islands and
Bahamas are likely to feel the effects of storm swells by early on Thursday, and the US East
Coast by the weekend.
“These swells are likely to cause life-threatening surf and rip current conditions”, the
NHC warned.
Mexico's Yucatan Peninsula was hit by heavy rain and wind as Karl made landfall.
Hurricane Karl's maximum sustained wind speed is put at 160 km / h (100 mph). The
NHC said it could increase to major hurricane strength before making its next landfall
sometime on Friday.
When the storm passed over Yucatan, the sparsely populated peninsula was hit by
heavy rain.
The NHC warned that up to 20 cm (eight inches) of rain could fall, causing “life-
threatening flash floods and mud slides” particularly in mountainous areas.
Twenty-five people are reported to have been killed and almost a million people
been affected by floods already this month in Mexico, which is in the grips of its annual
rainy season.
Following Karl's increase in power, a hurricane warning was issued for Mexico's
coast from Palma Sola to Cabo Rojo, and a tropical storm warning issued for the stretch
of coast from Cabo Rojo to La Cruz to the north of the storm and from Palma Sola to
Veracruz in the south.
Karl is currently located about 335km to the south-east of Tuxpan, Mexico, moving
westwards at a speed of about 19 km / h.
It is threatening to “pass very nearby” Pemex oil company installations, Jaime Albarran
of the National Weather Service told AFP news agency.
The Mexican state-owned oil operator evacuated workers from 14 oil platforms “as
a precaution”, and shut down production.
