The storm formerly known as Potential Tropical Cyclone 26 intensified rapidly yesterday to a tropical storm yesterday morning and grew to a hurricane just 12 hours later. Hurricane Delta could reach Category 4 by Tuesday evening, when it is expected to hit the Yucatan Peninsula. Forecasters predict it will hit the American Gulf Coast late this week as a Category 2. Hurricane Delta will be the second storm to hit the Yucatan Peninsula this week. By increasing sea surface temperatures, climate change is making hurricanes more intense and is making rapidly intensifying storms more common.
