Bud formed close enough to southwestern Mexico to trigger a watch. The National Hurricane Center issued a Tropical Storm Watch from Manzanillo to Cabo Corrientes, Mexico.

The National Hurricane Center noted winds, heavy rain and dangerous ocean swells are likely. NHC said on June 11, "Bud is expected to produce total rain accumulations of 3 to 6 inches across much of southwestern Mexico, with isolated maximum amounts of 10 inches into Tuesday afternoon. These rains could cause life-threatening flash floods and mud slides. In addition, ocean swells generated by Bud will continue to affect portions of the coast of southwestern Mexico during the next few days. These swells are likely to cause life-threatening surf and rip current conditions. Tropical storm conditions are possible within the watch area beginning this afternoon, June 11.
