In the Gulf of Mexico last week a huge storm was brewing, as rapidly warming surface waters hit the crucial temperature of 80.6F (27C). Powered by heat transference from the sea surface, cyclones like Hurricane Alex rampage across the coastal regions of the southern states every summer. But this year Alex, and the storms that will follow, threaten to bring extra misery, spreading the huge oil slick further and wider from the stricken Deepwater Horizon rig.
Alex, the first hurricane of the season – and the first June hurricane in the Atlantic basin for 15 years – is the last thing clean-up staff need as they struggle to contain the disaster.
“Already clean-up efforts have been greatly hampered by the storm,” says Professor Ronald Kendall, head of environmental toxicology at Texas Tech University. “This is very early in the season to have a storm the size of Alex. This does not bode well for the months to come.”
The US National Oceanic and Atmospheric Administration agrees, predicting an “active to extremely active” hurricane season this year. The movement of the storms will be crucial. Those coming from the south-west are likely to move the oil out into the Gulf. Storms coming from the east risk flooding the coastal areas.
But the immediate concern is that storms will undermine the drilling of relief wells, which many consider the best hope of stopping the leak. BP is trying to bore two auxiliary channels into the well to fill them with mud and concrete and plug the hole.
