The second named tropical cyclone of the [[2007 North Indian Ocean cyclone season]], Gonu developed from a persistent area of [[convection]] in the eastern Arabian Sea on June 1, 2007. With a favorable upper-level environment and warm [[sea surface temperature]]s, it [[rapid intensification|rapidly intensified]] to attain peak winds of {{convert|240|km/h|mph|abbr=on|round=5}} on June 4, according to the [[India Meteorological Department]]. Gonu weakened after encountering dry air and cooler waters, and early on June 6, it made [[landfall]] on the easternmost tip of [[Oman]], becoming the strongest tropical cyclone to hit the [[Arabian Peninsula]]. It then turned northward into the [[Gulf of Oman]], and dissipated on June 7, after making landfall in southern [[Iran]], the first cyclonic landfall in that country since 1898.

Intense tropical cyclones like Gonu are extremely rare in the Arabian Sea, and most storms in this area tend to be small and dissipate quickly.<ref>{{cite web|url=http://earthobservatory.nasa.gov/NaturalHazards/view.php?id=18436|title=NASA Earth Observatory: Tropical Cyclone Gonu|date=June 4, 2007|access-date=January 2, 2014|publisher=NASA|archive-url=https://web.archive.org/web/20140927024934/http://earthobservatory.nasa.gov/NaturalHazards/view.php?id=18436|archive-date=September 27, 2014|url-status=dead}}</ref> The cyclone caused 50 deaths and about $4.2 billion in damage (2007 USD) in Oman, where the cyclone was considered the nation's worst natural disaster. Gonu dropped heavy rainfall near the eastern coastline, reaching up to 610 mm (24 inches), which caused flooding and heavy damage. In Iran, the cyclone caused 28 deaths and ${{Formatprice|216000000}} in damage (2007 USD).

In Oman, production of [[desalination|desalinated water]] was interrupted, as both of Oman's desalination plants failed. The first, Ghubrah, lost supplies of [[natural gas]], halting production; while the second, Barka, sustained a damaged switchgear due to flooding. These plants provided water to Muscat's 631,000 residents and surrounding areas, triggering severe water shortages across eastern Oman. To rectify the situation, officials used water tanks. The water returned to near normal in five days, as the two plants returned to service.
