The upper level winds are weak near the center of the upper level ridge. So, there will be little vertical wind shear. Tropical Storm Pilar is likely to intensify gradually during the next 24 hours.

Tropical Storm Pilar will move into a region where the steering currents are weak during the next 24 hours. Pilar is likely to continue to move slowly toward the east-northeast on Tuesday.
