Titli was the twelfth depression and fifth named storm to form in the 2018 North Indian Ocean cyclone season.

Titli continued to intensify at it moved toward the southeast Indian coast, becoming a very severe cyclonic storm, equivalent to a minimal hurricane on the Saffir–Simpson scale.

Late on October 10, Titli made landfall in Andhra Pradesh, and it quickly weakened over land as it turned to the northeast.

The cyclone produced strong winds, with gusts to 126 km/h (78 mph), along with a storm surge that flooded coastal areas.

This caused floods and landslides, crop damage, fallen trees, and power outages that affected at least 400,000 people.

As early as October 3, the India Meteorological Department (IMD) anticipated the development of a tropical cyclone in the Bay of Bengal.

Environmental conditions for development included warm sea surface temperatures up to 31 °C (88 °F) and low wind shear.

Early on October 7, a low pressure area developed in the Andaman Sea, accompanied by intense convection, or thunderstorms.

With tropical cyclone forecast models uncertain about the system's future, the American-based Joint Typhoon Warning Center (JTWC) assessed a low chance for development on October 7.

[4] As it approached the coast of India, Titli underwent rapid deepening as its structure evolved into a mature cyclone.

Early the next day, Titli strengthened further into a very severe cyclonic storm, as an eye formed in the center of the thunderstorms.

[5] Late on October 10, Titli made landfall near Palasa, Andhra Pradesh, at peak intensity, as its eye contracted to a diameter of 12 km (7.5 mi).

[1] The storm quickly weakened over land as it turned to the northeast through Odisha state, encountering cooler, drier air as it moved around the western end of the ridge.

[1] In Gajapati district in Odisha, a single landslide killed 12 people, after residents sought refuge in a cave.

[19] Two major rivers, the Rushikulya and the Vamsadhara, swelled to reach dangerous levels, causing flooding in three districts that affected more than 600,000 people.

[15] Caritas India, a Catholic relief organization, provided families with sheeting and cleaning, including mosquito nets, blankets, and tarpaulins.

[25] Cyclone Titli's effects extended into Bangladesh, where Cox's Bazar recorded three days of heavy rainfall.
