The India Meteorological Department (IMD) has forecast extremely heavy rainfall in several Kerala districts on August 28 and 29. According to IMD, the heavy rains have been triggered by a cyclonic circulation over northwest Bay of Bengal. "A low pressure area is likely to form over northwest and adjoining western central Bay of Bengal by August 28. In view of all these, increase in rainfall activity is expected over Kerala during 27-29 August," IMD said.
