Typhoon Bavi undergoes eyewall replacement, may reach fourth peak intensity

Typhoon Bavi is showing signs of an eyewall replacement cycle, a phenomenon that could lead to a fourth peak in its intensity, according to the weather fan page "Taiwan Typhoon Forum - Weather Express."

The typhoon's storm radius has expanded to 380 kilometers. Recent satellite imagery reveals a clear eye, but a developing outer eyewall suggests the replacement process has begun. The fan page noted that the typhoon's structure is becoming asymmetrical due to vertical wind shear from the northeast.

Currently, Bavi is experiencing a trend of gradual weakening due to the strong vertical wind shear and the ongoing eyewall replacement. However, if the replacement cycle is successfully completed, the typhoon could reach a fourth peak in intensity. Despite this potential, the current environmental conditions are making the replacement process more challenging.

Even with a slight decrease in intensity, the typhoon's broad wind field means its strong winds will still pose a significant threat. Further observation is needed to determine how the eyewall replacement will alter Bavi's circulation pattern and its ultimate trajectory.
