How does Hurricane Hermine measure up?
On Friday Hurricane Hermine made landfall in Florida, making it the first to make landfall in the state in more than a decade.
Hermine, which weakened to a tropical storm shortly after landfall as is commonly the case with weak hurricanes, was poised to redevelop and pose a threat to the Mid-Atlantic states and possibly southern New England into the middle of the week. Continue reading

What is a heat wave?
A heat wave is a period of abnormally and uncomfortably hot and usually humid weather. The World Meteorological Organization is specific in its definition by stating that a heat wave is when the daily maximum temperature for more than five consecutive days exceeds the average maximum temperature by 9 degrees.
Heat waves are caused by very hot, stagnant air masses. Regions that suffer under intense hot spells are usually dominated by a surface high-pressure system with a mid-tropospheric ridge aloft. Dew points are also high, and to compound matters, wind speeds are often low. Continue reading
