A heat wave pushed temperatures above 110 °F on the eastern edges of Delhi. Rolling blackouts came and went. In poor districts along the border with Uttar Pradesh, many families slept on their roofs. The first report came from Ghaziabad, dated to 5 April 2001, although Reuters placed the first attack there in early May. By around 12 May the thing had reached Delhi, and by 16 May it was being reported in Noida and New Delhi.
