Many parts of the coastal districts and some interior parts of Orissa are likely to experience heavy to very heavy rain fall during the next two days. The Bhubaneswar Meterological Office has said this is due to formation of low pressure area over West-Central Bay of Bengal.It has also predicted the system to be more marked. Though the wind speed during the rain will be more or less normal, fishermen have been advised not to venture into the sea. Under the experience of the low pressure, drizzle continues in many cities including Bhubaneswar since early Wednesday morning.
