In contrast to other areas where tropical cyclones formed , such as the Pacific hurricane season , the cyclone season in the Northern Indies in 1990 was not limited in time, but year-round. However, cyclones occur mainly before and after the summer monsoon , in May and June and in October and November. The responsible Regional Specialized Meteorological Center , the India Meteorological Department (IMD), counts all storms that form between 45th and 100th degrees east. In this basin, the cyclones arise either east of the Indian subcontinent in the Bay of Bengal and in the Arabian Sea to the west .
