Typhoon Vamco is being as stubborn in its quest to live in the Pacific Ocean as Bill is in the Atlantic Ocean this week, and NASA satellite data confirmed that the large storm has a huge eye, about 45 miles in diameter!

NASA’s Aqua satellite flew over Typhoon Vamco early today, Monday, August 24, and infrared imagery from Aqua’s Atmospheric Infrared Sounder (AIRS) instrument clearly showed Vamco’s 45-mile in diameter eye. Around the huge eye, AIRS showed Vamco’s cold high thunderstorm cloud temperatures were colder than minus 63 Fahrenheit. That’s an indication that the storm is still strong, and it is still a category one typhoon.

Also on NASA’s Aqua satellite, the Moderate Imaging Spectroradiometer (MODIS) instrument captured a stunning look at Typhoon Vamco’s clouds at 0255 UTC (August 23 at 10:55 p.m. EDT).

On August 24, Vamco was 990 miles northwest of Wake Island, near 32.1 north and 155.0 east. It was moving north near 12 mph and had sustained winds near 85 knots (97 mph) creating 25 foot-high waves in the open ocean. Typhoon Vamco is maintaining strength and will start to weaken later as upper-level winds start to batter the storm.

… Typhoons are the same as hurricanes, but known as “typhoons” west of the International Dateline. Vamco is now category 2 typhoon on the Saffir-Simpson Scale and is forecast to be a category 4 typhoon by Thursday evening, Eastern Time.

… Fortunately no land masses are threatened however, shipping interests in the northern Pacific should this keep apprised of this storm. The storm is headed in a northerly direction.
