Typhoon Songda (Chedeng) Update #16

Songda (Chedeng) is now undergoing what is called the eyewall replacement cycle. Several concentric rings around the eyewall can be seen on this microwave image from NRLMRY:

Songda was last located approximately 250km east of Aparri, Cagayan. Due to the eyewall replacement cycle, maximum sustained winds have decreased to 240kph with gusts to 280kph. Songda is downgraded to a Category 4 typhoon.

As of 11am today, PAGASA has raised Signal warning #2 for Babuyan and Batanes Group of Islands. Signal #1 for Cagayan, Isabela, Aurora, Quirino, and Apayao.

Unfortunately PAGASA's Doppler radar in Baler is not available to the public. Thankfully, Taiwan's radar is accessible through the CWB website. The image includes Basco, Batanes and in this latest capture you can see outer rainbands beginning to affect the islands. Moderate to heavy rain should continue throughout today.

Our forecast track will be posted later on our 330pm update.
Issued (330 UTC) 1130am PhT 052711
