The storm developed from a tropical disturbance in the monsoon trough and moved generally westward throughout its duration.

The storm ultimately peaked in intensity as a super typhoon and struck northern Luzon in the Philippines.

The origins of Typhoon Angela trace back to a tropical disturbance in the monsoon trough that became very active after a lull in convection.

The disturbance developed over the western Caroline Islands, and persisted for two days until it was noted in a Significant Tropical Weather Advisory issued by the Joint Typhoon Warning Center (JTWC).

[1] At 0600 UTC on September 28, the Japan Meteorological Agency (JMA) recognized the storm as a tropical depression.

The system initially tracking northwestward, Angela turned westward along the southern periphery of a subtropical ridge to the north.

[1] The JMA then upgraded Angela to a typhoon shortly thereafter, and assessed it as having reached peak intensity on October 2, with 10-minute maximum sustained winds of 175 km/h (110 mph) and a minimum barometric pressure of 925 millibars.

[1] The storm weakened after interacting with land, and the JTWC downgraded it to a typhoon on October 6 as it emerged into the South China Sea.

3 the next day, and after the typhoon's closest approach to the region on October 8, a Strong Monsoon Signal was hoisted.
