Flooding in Chihuahua, Mexico has claimed life of a person and closed an International Airport. Heavy rains caused the Cacahuateles and Nogales Rivers to overflow which flooded the Chihuahua International Airport in Northern Mexico. Chihuahua has received the rainfall in three hours equivalent to an entire year causing huge flood damage.

'Brown Ocean' Can Fuel Inland Tropical Cyclones

Before making landfall, tropical storms gather power from the warm waters of the ocean. When storms move over land, they normally lose power. A handful of tropical storms and hurricanes have defied the odds and strengthened over land. Now researchers believe they have a better understanding why this occurs.

Tropical systems are expected to weaken while interacting with land, but if conditions are ideal, a land mass can feed these entities and act as a "brown ocean." A recently released study, funded by NASA and conducted by Drs. Theresa Andersen and Marshall Shepherd of the University of Georgia has found that abundant soil moisture can continue to feed a tropical storm or hurricane long after it has left the warm waters of an ocean.
