. But when a reconnaissance hurricane hunter aircraft flew in, they only found a broad area of low pressure, with no closed or low level circulation, despite the fact that satellite photo shows the system developing very well.

However, only a few hours later satellite photos also showed some convective bands from the system, so it was declared a tropical depression on June 18, Tropical Depression Two to be more specific. The center of the storm was south of a low pressure system to the north and that low forced the depression to move west-northwest. During another flight into the storm, the hurricane hunter crews reported a 1006 mbar reading but could not get an accurate fix. On June 19, a comma shaped band of thunderstorms formed around the center this caused slightly strengthening and further organization. The National Hurricane Center upgraded the depression to a tropical storm on that same day at 1200 UTC and new tropical storm received the name Arlene, therefore it was reclassified as Tropical Storm Arlene. Arlene moved northwestward at 2 to 3 mph (3.2 to 4.8 km/h) before nearly stalling because of a frontal system passing by. On June 20, Tropical Storm Arlene made landfall over Padre Island
