Typhoon #Kajiki has likely reached its peak intensity after passing to the southwest of the Chinese island of #Hainan on Monday morning. Cooler waters near the coast of #Vietnam will cause the storm to weaken further before it makes landfall later this afternoon.

Meanwhile, #Invest90W has made landfall over #Luzon in the northern #Philippines this evening. Environmental conditions appear to be supportive of tropical cyclone development once the disturbance emerges over the South China Sea overnight.

The Seven-Day Graphical Tropical Weather Outlook from the National Hurricane Center, which depicts Hurricane Erin off the U.S. East Coast and three disturbances—Invest 90L near the Leeward Islands, Invest 99L over the central tropical Atlantic, and a weak area of low pressure over the central subtropical Atlantic. Of the three disturbances, Invest 90L is the likeliest to become at tropical cyclone within the next two to five days as it turns northward toward Bermuda.

#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.

Tropical Storm #Erin will gradually turn west-northwestward as it moves along the base of a subtropical ridge this week. By the weekend, a break in the ridge will form east of the #Bahamas, allowing Erin to turn northwestward to north-northwestward.

🌀 Erin's track takes it north of but fairly close to the Leeward Islands of the NE Caribbean. This region should monitor the forecast & be prepared for potential impacts

A graphic depicting the current position of Tropical Storm Erin and the two-day forecast from the National Hurricane Center. Although the storm is currently struggling within a dry environment, conditions should begin to improve as the storm races westward toward the Leeward Islands this week. Erin is forecast to become a hurricane by Thursday and pass to the north of the islands as a major hurricane later in the week.
