A Category 5 Typhoon (Hurricane) in the Western Pacific!

  Typhoon MEGI, which reached category 5 strength a couple of days ago while over the Philippines Sea, in the western Pacific, made landfall in the island of Luzon, the Philippines, and is back to category 3 strength after emerging over the South China Sea aiming for Hong Kong and the mainland of China. This region of the western Pacific has been particularly active during 2010.

On the opposite side of the globe, the Caribbean near Central America continues to be quite active. Where just over one week ago tropical storm Paula formed off the coast of Nicaragua near cape Gracias a Dios, near the Nicaragua-Honduras border, we now have a large tropical wave with organized rain shower activity moving North-Northwest toward the Yucatan Chanel. There appears to be a favorable environment ahead of this tropical wave making it possible that it might develop further over the next 24 – 48 hours, however this system may have to contend with a front descending toward the southeastern USA and the Gulf, which may affect its track just as Paula was affected a week ago.

Satellite view of the eastern Atlantic for the aviation industry on 19 October 2010; several tropical waves moving westward are visible

 

Looking toward the distant eastern Atlantic there are several small tropical waves riding along Hurricane alley and over Equatorial Africa. These waves appear to be smaller and weaker than those seen in August and September, and they are active closer to the equator, which takes them on a more southerly route than those in late summer. Regardless, it is important to monitor these weather systems as they make their way toward the Caribbean and the Antilles and get closer to our neck-of-the-woods.

Full-disk satellite view of Earth's western hemisphere on 19 October 2010. The 'belt' of tropical activity has narrowed and shifted somewhat to the south as autumn takes over the northern hemisphere. Lots of storm and rain activity can be seen over Ecuador, southern Colombia and Venezuela, and over large regions of Brazil.
