Tropical Storms Nana and Omar likely to form this week
While there's a good chance that Tropical Storms Nana and Omar will form this week, neither of them are likely to threaten the United States. The 2nd image shows the Euro ensembles for the next 15 days.
The following is from the National Hurricane Center on the 4 systems of interest:
1. A westward-moving tropical wave accompanied by a broad low pressure area is located over the eastern Caribbean Sea just west of the Windward Islands. Associated shower and thunderstorm activity continues to show signs of organization, and environmental conditions are expected to gradually become more conducive for development. A tropical depression is likely to form during the next day or two while the system moves moves westward at about 15 mph across the central Caribbean Sea. Interests in Jamaica, Honduras, Belize, Guatemala and Yucatan should monitor the progress of this disturbance. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...80 percent. 2. An area of low pressure is expected to form off the southeastern coast of the United States in a day or two. Subsequent development of this system is possible, and a tropical depression is likely to form by the middle of the week while the system moves northeastward or east-northeastward, initially parallel to the southeastern coast of the U.S. and then away from land. * Formation chance through 48 hours...medium...60 percent. * Formation chance through 5 days...high...70 percent. 3. A new tropical wave is expected to emerge off the coast of Africa in a couple of days. Gradual development of this system will be possible through the end of the week while it moves slowly westward over the far eastern tropical Atlantic Ocean. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...low...30 percent. 4. A westward-moving tropical wave is located over the eastern Atlantic Ocean, several hundred miles southwest of the Cabo Verde Islands. This system is producing limited shower activity, and further development is becoming less likely due to unfavorable environmental conditions. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...low...20 percent.
