Rainfall Forecast issued by India
Meteorological Department for today and tomorrow indicate that Heavy rainfall
is likely in North Konkan North Madhya Maharashtra and Gujarat State during the
next 24 hrs in association with Ockhi Cyclone which is likely to cross the
coast near Surat. Likely formation of a depression in Bay of Bengal with
associated heavy rainfalls in North Coastal Andhra Pradesh and South Odisha on
December 07 and 08, 2017.
Due to this rivers in North
Konkan, North Madhya Maharashtra and Gujarat State are likely to rise rapidly.
The likely impact of these rains as inferred from rainfall runoff model run for
three days advisory forecast is likely rapid rise in the river levels in the
following basins as under:
Godavari Basin: River Godavari
and its tributaries in North Madhya Maharashtra in Nasik district are likely to
rise. As the rainfall is likely to affect only a very small catchment area of
this basin not much effect will be felt in the river Godavari and its
tributaries.
West Flowing River South of Tapi:
Rivers
Damanganga and its tributaries in districts of Nasik in Maharashtra, Valsad in
Gujarat and Daman in UT of Diu and Daman are likely to rise. However as the
rainfall will be only for one day no major flooding is expected in the basin.
Mahi Basin: River Mahi and
its tributaries in Gujarat may rise in association with heavy rainfall in the
districts of Mahisagar, Panchmahal, Kheda and Vadodara. However, as the
rainfall will be effective for only one day not much flooding is expected
except for some rise in the river in the areas affected by heavy rainfall.
Sabarmati Basin: River Sabarmati
and its tributaries also may not see any major flooding. However, the river may
rise in some areas which are directly affected in the path of the cyclone which
would have weakened sufficiently by the time it reaches this basin.
East Flowing Rivers between
Mahanadi and Godavari: Rivers Rishikulya, Vamsadhara and Nagavali in South
Odisha and North Andhra Pradesh Coast are likely to rise in association with
heavy rainfall which is expected on December 06 and 07, 2017 in association
with likely movement of depression over Andhra Pradesh. General vigil may be
kept in these catchment areas in the districts of Gajapati, Rayagada,
Srikakulam, Vizianagaram for rapid rise in water levels.
Indravathi and Sabari Basins of
Godavari Basin:
Rains in South Odisha and Noth Coastal Andhra Pradesh may lead to rise in water
levels of Sabari basins in Nowrangpur, Malkangiri,Koraput and East Godavari
districts.
Krishna and its tributaries: River Krishna
and its tributaries such as Paleru, Munneru, Wyra alongwith main Krishna
downstream of Pulichintala may get inflows in association with the rainfall in
Krishna and Guntur districts of Andhra Pradesh.
Pennar Basin: River Pennar and
its tributaries in South Andhra Pradesh may get some inflows in association
with rainfall over Coastal Andhra Pradesh in the district of Nellore in Andhra
Pradesh.
As the path of the depression is
not yet well established, sufficient vigil may have to be maintained in Coastal
Areas of North Tamilnadu (Chennai, Kanchipuram, Tiruvallur, Cuddalore,
Villupuram districts) Andhra Pradesh (from Nellore to Srikakulam districts) and
South Odisha during the next three days.
