Annual monsoon rains have progressed to parts of western and central India, easing fears of millions of desperate farmers after two straight years of drought, the weather department said. Farmers rely on the monsoon rains, which hit the Kerala coast every year and then sweep across the country, to water their crops and replenish dams and reservoirs. The arrival of the monsoon is always keenly watched in India, but even more so this year as much of the country reels from the drought. / AFP PHOTO / INDRANIL MUKHERJEEINDRANIL MUKHERJEE/AFP/Getty Images

(FILES) This file photo taken on June 11, 2016 shows Swiss pilot Andre Borschberg (R) and Swiss pilot Bertrand Piccard celebrating after the successful landing of the Solar Impulse 2 aircraft at JFK International Airport in Queens, New York. The Solar Impulse 2 aircraft will take off from New York early June 20, 2016 on the transatlantic leg of its record-breaking bid fly around the globe using only solar energy. The plane had been due to leave early June 19, but this was put off, apparently because of concerns over the weather. Takeoff for Seville in Spain is now scheduled for 2:00 am (0600 GMT), the Solar Impulse team said on Twitter. The flight over the ocean is scheduled to last 90 hours, during which solo pilot Bertrand Piccard will only be able to take short naps. / AFP PHOTO / EDUARDO MUNOZ ALVAREZEDUARDO MUNOZ ALVAREZ/AFP/Getty Images
