Tropical Depression #14 moving west in the southern Caribbean

Tropical Depression 13 forms

Several models show the paths of the storms colliding sometime Monday afternoon or Tuesday morning, and if this occurs, the "fujiwara effect" could cause the 2 growing storms to become one massive mega-hurricane. By the middle of next week, the storm should make landfall somewhere along the Texas or Louisiana coast. The system has already triggered a hurricane watch for Cancun and other parts of Mexico's southeastern coast.

A tropical storm watch is in effect for the Honduras/Nicaragua border west to Punta Castilla, Honduras and for the Bay Islands of Honduras.

"A lot of people are going to be impacted by rainfall and storm surge in the Gulf of Mexico", said National Weather Service Tropical Program Coordinator Joel Cline.

Tropical Depression 14, which will become Tropical Storm Marcos if it develops as forecasters expect, will likely arrive first. Some weakening is expected as it moves over the Yucatán Peninsula Saturday night.

Those areas should monitor the progress of this system.

There is the potential for flash flooding and landslides. This wave is expected to move farther offshore over the far eastern tropical Atlantic today. The system is packing 35 miles per hour winds and is moving west-northwest at 21 miles per hour.

Two tropical systems could become almost simultaneous threats to the U.S. Gulf Coast early next week. It will become a tropical depression on Friday evening and a remnant low by Saturday.

With competing scenarios, the hurricane center is forecasting a middle range for Laura of a weak hurricane heading into the eastern Gulf of Mexico. Multiple factors contribute to the strength and direction a hurricane travels, including wind, ocean temperatures and the overall atmospheric pattern, which steers the storm.
