The first tropical storm of the season in the eastern North Pacific (TS Andres) is moving NNW off the Southwest Coast of Mexico today and will likely impact shipping routes to and from the Panama Canal between Acapulco and Cabo San Lucas during the next few days. Andres is forecast to strengthen approaching hurricane intensity as it passes near Manzanillo PM Tuesday.
