A newly formed tropical depression (#10E) is expected to gradually strengthen as it moves west-northwestward away from southwestern #Mexico over the next couple of days. This system will reach unfavorably cooler waters and weaken later this week.

Tropical Storm #Fernand is gradually strengthening as it passes well to the east of #Bermuda this afternoon. Further intensification is possible as the storm remains over warmer waters over the next day or so. The storm will enter a less favorable environment on Tuesday and will weaken.

#Erin continues to produce a very large wind field, which is only expected to continue to expand as it becomes an extratropical cyclone this weekend. Life-threatening surf and rip currents will continue along the U.S. East Coast, the Bahamas, Bermuda, and Atlantic Canada through next week.

The graphic also depicts the forecast for the next five days—Erin will continue northeastward across the northern Atlantic and will remain a powerful extratropical cyclone off the coast of Ireland midway through the upcoming week.

Satellite imagery analysis reveals that Hurricane #Erin is undergoing extratropical transition as it passes to the east of New England this morning. Strong southwesterly shear has exposed its circulation and cold air is rushing in behind the storm.

🌊Storm surge flooding and tropical storm conditions are expected in the North Carolina Outer Banks beginning later today (Aug. 20). The storm surge will be accompanied by large waves, leading to significant beach erosion and over wash, making some roads impassible.
