熱帶氣旋形成警報
Early on June 21, the JTWC reported that an area of low pressure had persisted about 675 km, (420 miles), southwest of Mumbai, India. Multispectral imagery showed that the disturbance had a developing low level circulation center with convection flaring over it and was in an area of low vertical wind shear. Over the next couple of days the disturbance developed gradually with a Tropical Cyclone Formation Alert being issued early on June 23 as the disturbance had continued to organize and consolidated over the past few hours. RSMC New Delhi then reported later that morning that Depression ARB 01 had formed and was expected to intensify into a Deep Depression before making landfall, however the depression did not intensify any further before making landfall on the south Gujarat coast near Diu. The JTWC then cancelled their Tropical Cyclone Formation Alert, with the IMD issuing their final advisory later that day. It hovered over Gujarat as a well marked area of low pressure before moving towards the northeast and re-emerging into the Arabian Sea where it redeveloped into a depression. Tropical Depression ARB 01 dissipated early on June 26.
