Christened Isaias, pronounced (ees-ah-EE-as), the hurricane that formed on Wednesday over the Caribbean Sea packs maximum sustained winds of 50 mph and is zipping northwest at 20 mph, says the National Hurricane Center (NHC).
"The eventual track will determine Isaias' strength and potential future development," CNN Meteorologist Chad Myers said. "A track mainly over water will let the storm get stronger. A path more over land and the mountains of Hispaniola and Cuba will help to tear it apart."
However, once it gets over warmer waters, the storm could strengthen quickly like what was seen with Hurricane Hanna last weekend. Something, many of the models struggled to pick up on.
Hurricanes get stronger when the surface water is warm, because the storm sucks up heat energy from the water, just like a straw sucks up a liquid. ... This heat energy is the fuel for the storm. And the warmer the water, the more moisture is in the air. And that could mean bigger and stronger hurricanes.
Rainfall will be the main concern over the next few days. Over 3 to 6 inches could fall across the Virgin Islands, Puerto Rico, Dominican Republic, Turks and Caicos, eastern Cuba and northern Haiti. The southeastern Bahamas could see 4 to 8 inches. This could lead to flash flooding, mudslides and potential riverine flooding.
Tropical storm warnings are issued for Puerto Rico, the US and British Virgin Islands, the entire northern and southern coasts of the Dominican Republic, and the north coast of Haiti from Le Mole St Nicolas to the border with the Dominican Republic. Tropical storm-force winds are expected within the warning areas.
There were Tropical Storm warnings issued before the storm even formed. The reason it was called "Potential Tropical Cyclone Nine" is because the storm did not have a round center of circulation, says CNN meteorologist Chad Myers. Instead, it was very elongated. "When a circular center finally formed, that is when they began to call it a tropical storm."
By calling it a potential tropical cyclone, it allowed countries to issue watches and warnings.
