The National Weather Service has announced that Hurricane Harvey is strengthening and aiming at the Texas coast of the Gulf of Mexico. Because of sea temperatures and climate conditions, if the storm pauses offshore, as the National Weather Service is warning that it may do, it has the potential to increase into a historic storm on the order of Superstorm Sandy or Hurricane Katrina. High water temperatures in the Gulf of Mexico mean that storm tops are being driven high into the upper atmosphere. Should they reach the zone of extreme temperature gradient that is now present in the upper levels of the stratosphere, the storm will undergo the same sudden expansion that characterized the other two recent historic hurricanes.
