 On September 13 , convection and organization increased and the depression strengthened into Tropical Storm Ingrid , while weak steering currents resulted in little movement of the cyclone . <unk> due to the presence of nearby Hurricane Manuel in the eastern Pacific basin on the other side of Mexico , significant wind shear existed in the vicinity of Ingrid . Nonetheless , strong convection and intermittent development of an eye allowed for strengthening of the storm on September 14 . Ingrid strengthened into a hurricane – the second of the season – that afternoon . Around that time , the hurricane turned sharply northeastward due to a trough over eastern Mexico and a ridge over the southeastern United States . Additional strengthening took place thereafter , and Ingrid reached a peak intensity of 140 km / h ( 85 mph ) early on September 15 while starting to move northward and begin a northwest turn towards the Mexican coastline .
