The India Meteorological Department (IMD) on Saturday said that rainfall is likely to continue over Kerala due to low pressure system formation over Arabian Sea. According to the IMD, the rainfall activity is to become active again in the coastal areas of Maharashtra and coastal Karnataka on August 10 and will remain so for the next seven days. The intensity of rain reduced gradually in the last two days. Due to low pressure system, heavy rainfall at isolated places would occur over East & West UP, East Rajasthan, Haryana, Northern parts of Punjab, Uttrakhand and Himachal Pradesh between August 10 and 12.
The IMD further said that the southwest monsoon will become active over northwest India likely to increase from August 9 to 11, onwards with heavy to very heavy rainfall very likely over Western Himalayan region and adjoining plains. India has received 522.6 mm rainfall as against the normal of 525.1 mm so far.
“Due to strong southwesterly and easterly monsoon flow prevailing over the Arabian sea, scattered heavy to heavy rainfall is likely to continue over Kerala and Maharashtra during the next 24 hours. Coastal Karnataka and south interior Karnataka is likely to experience extremely heavy rainfall in the next 24 hours,” K Sathi Devi, Senior Scientist, India Meteorological Department (IMD), said.
Due to low pressure system near Odisha, rainfall activity likely to increase over east and adjoining parts of central India with heavy to very heavy rainfall over Odisha during 9th to 11th and over Vidarbha and Chhattisgarh during 10th to 12th. Isolated extremely heavy falls also likely over Odisha on August 10.
Meanwhile, IMD study shows that whenever a low-pressure system forms near Odisha, rainfall scale up over Kerala. “Kerala - Idukki (Peermade)-176 mm, Kannur(Irikkur)-173, Kasargode(Vellarikkundu)-162, Kottayam (Poonjar)-141, Kottayam (Kumarakom)-82, Kozhikode (Kakkayam)-258, Palakkad(Adakkaputhur)-117, Pathanamthitta (Seethathode)-111, Wayanad (Padinjarathara_dam)-158, Kollam (Valiyapadam)-51, Ernakulam (North Paravar)-129, Allappuzha (Kanjikkazhy)-79, Thrissur(Poringalkuthu)-79, Chalakkuddy-81,” the IMD said.

During this period south westerly winds from Arabian Sea & easterly winds from Bay of Bengal will reach to Haryana, Delhi NCR and west Uttar Pradesh in lower levels.
“Under influence of this, moderate rain accompanied with one or two spell of intanse rain would occur over Delhi during evening /night of 9th to 12th August. Thunder storm would also occur during above mentioned period. Isolated Heavy rain may also occur over NCR,” the IMD said.
