A tropical wave looks to come off the coast of West Africa over the next 72 hours. TIMELINE: As we progress through mid to late week, data suggest at least the potential for a tropical depression or tropical storm. This could become Tropical Storm Cristobal by later next week, but there is a lot of wind shear in the tropical Atlantic. That is making for lots of wind shear across the Basin. The strong ridge of high pressure in the Atlantic should help steer this system out into the open Atlantic and keep it away from any major landmass.
