Wet and more wet for soggy Delhi

Another week of rain is expected to further hinder late Commonwealth Games preparations while rivers rise to danger levels in host city New Delhi.

Less than two weeks out from the Games, the protracted monsoon season has resulted in flood levels not seen in 32 years for the Yamuna River, which flows within a few kilometres of the athletes village.

Forecasts from Weather Channel Australia show an 80 per cent chance of thunderstorms in the Games city until Saturday.

The Yamuna rose 0.87 metres above danger levels on Monday evening (Delhi time) and is expected to rise another 0.7 metres on Tuesday, according to Indian media reports.

The last time such high levels were seen was in 1978, when the river rose 3.5 metres above designated danger levels, according to the website of India's Department of Irrigation and Flood Control.

From June 1 this year, Delhi has received more than 890mm of rain while the average for that period is 645mm, the department says.

Games' organisers have acknowledged that the persistent monsoon rains contributed to construction delays for the 17 Games venues.

Delhi has also recorded more than 2200 cases of dengue fever - the waterborne disease carried by mosquitoes. That figure is 10 times the normal annual infection rate.

Water has accumulated in pools around the venues and athletes' village, sparking concern about the health of Games participants.

Delhi authorities have issued assurances that crews are working constantly by spraying insecticides to rein in the outbreak.
