Jaipur, Sept. 19 -- The southwest monsoon is likely to begin withdrawing from Rajasthan from September 19, even as its final phase continues to bring heavy spells of rain to several parts of the state, particularly southern and southeastern districts. The India Meteorological Department (IMD) said on Friday that a low-pressure area over the region had weakened and was now lying as a cyclonic circulation over southern Rajasthan, Gujarat and adjoining areas. A western disturbance is also active over the state, with both systems influencing rainfall activity. Under their influence, very heavy rainfall was recorded at isolated places in the Udaipur division during the past 24 hours, while heavy rainfall occurred at isolated locations in the Bharatpur, Jaipur and Ajmer divisions. Rain continued intermittently from Thursday night to Friday afternoon across several areas of Udaipur, Salumber and Chittorgarh districts. In Salumber's Jhallara area, the Sarni river began flowing over the bridge, disrupting road connectivity. In Dungarpur's Aspur area, the Punjela dam at Punpur filled to capacity and a sheet of water about one foot deep began flowing over the dam on Friday morning. Continuous rain also caused several ponds to overflow and increased inflows into dams. The Maiyala pond in Mowai, Hariyala Kheda pond in Khalil and Gamela pond in Aspur were among the water bodies reported to be overflowing following the rainfall. In Chittorgarh district, rain began in Rawatbhata around 1.30 am on Friday and continued until morning. The rainfall triggered a strong flow at Dabko waterfall on the Brahmani river, as water levels rose. Banswara also witnessed renewed monsoon activity after a prolonged wait. Intermittent rain, ranging from drizzle to heavy spells, continued from Friday morning. Water began flowing across roads in parts of the city, including Azad Chowk. In Dungarpur's Aspur, rain has continued since around 3 am on Thursday, leading to rising water levels in local ponds and dams. The latest spell follows heavy rain across several districts on Thursday. Jaipur, Ajmer and other areas received up to four inches of rain, while night-long rainfall in Tonk caused damage to harvested crops lying in fields. The rainfall also affected local infrastructure. At Kota Junction, a fire broke out in an electrical panel following Thursday's rain. Officials said the fire was brought under control within a few minutes. The IMD said rainfall activity is likely to continue over parts of southeastern and eastern Rajasthan on September 19 and 20, with isolated areas likely to receive moderate to heavy rain. However, rainfall activity is expected to decline over parts of western Rajasthan during the next one to two days, with atmospheric conditions becoming favourable for the withdrawal of the monsoon. From September 21, most parts of the state are likely to experience predominantly dry weather, according to the weather department. The late-season rainfall has brought some relief to parts of southern Rajasthan and increased inflows into local reservoirs and water bodies. However, the distribution remains uneven, with western Rajasthan expected to see a decline in rainfall activity as the monsoon withdrawal process begins. The rain has also raised water levels across several local reservoirs. The weather transition over the next few days will therefore be crucial for the state's reservoirs and agriculture, particularly in areas that have received fresh rainfall after a prolonged dry spell....
