On June 8, an area of disturbed weather that had absorbed a tropical wave spawned Tropical Depression Two-E. It became a tropical storm the next day. After peaking on June 9, steering currents collapsed and Boris stalled out in the ocean between two ridges of high pressure. Shear increased, and the cyclone weakened to a depression on June 10. The next day, Boris degenerated into a remnant low. The remnant drifted east and then southeast before dissipating on June 12.
