Severe Tropical Storm Matmo[a] and Very Severe Cyclonic Storm Bulbul[b] (/ˈbʊlbʊl/) (JTWC designation: 23W) were a pair of destructive tropical cyclones that tracked in the Western Pacific Ocean and the North Indian Ocean in October and November 2019 respectively, killing 43 people and inflicting about US$3.537 billion in damage.

The cyclone formed on October 28 in the South China Sea and intensified into Tropical Storm Matmo, as named by the Japan Meteorological Agency (JMA).

Late the next day, it strengthened into a cyclonic storm, renamed Bulbul by the India Meteorological Department (IMD), although the JTWC continued to refer to it as Matmo.

On November 9, the cyclone made its final landfall in the eastern Indian state of West Bengal, and around that time the storm turned to the northeast, moving into Bangladesh.

[1][2][3] In addition, it is only the second storm to reach hurricane-equivalent strength in the Bay of Bengal after moving over Mainland Southeast Asia, the first being another cyclone in October 1960.

It quickly intensified into a severe tropical storm, packing 10-minute sustained winds up to 60 mph (95 km/h), as it approached the Vietnamese coast.

A quick moving storm, Matmo made landfall in Vietnam on the same day, bringing strong winds and heavy rain, causing moderate flooding and many road closures in the country.

[18] Matmo destroyed 2,700 houses and 35 schools, causing 912 billion VND (US$39.4 million) in damage in Vietnam, with majority of losses in two provinces: Quảng Ngãi and Bình Định.

[23] In Odisha, the cyclone's outer bands produced heavy rain and squalls, causing agricultural damage, uprooting trees, and knocking down power lines.

[27] Bulbul's landfall in West Bengal around the Sunderban forest brought extremely heavy rain and winds up to 137 km/h (85 mph) across much of the southern portion of the state.
