Additionally, steering currents that had been taking Leslie southwestward over the previous several days completely collapsed, resulting in the hurricane becoming stationary.[20] Six hours later, at 15:00 UTC, Leslie reached its initial peak intensity with maximum sustained winds of 130 km/h (81 mph) and a minimum central pressure of 975 hPa (28.79 inHg).[21] At 21:00 UTC, Leslie began to move northward, under the influence of a shortwave trough to the northwest and a mid-level ridge to the southeast.[22]
