Cristobal, which is no longer tropical, continues to race northeastward across the North Atlantic and will impact Iceland with some gusty winds and heavy rain over the next few days. The remainder of the tropical Atlantic remains unusually quiet for Labor Day weekend with no named systems and no imminent development.
A tropical wave moving through the northwestern Caribbean continues to gather moisture as it nears the Yucatan Peninsula. Eventually, as the tropical wave emerges into the southern Gulf of Mexico, development into a tropical depression or tropical storm is not out of the question as conditions become a bit more favorable for development. Through time, the feature is likely to continue to move westward and, at the very least, bring enhanced showers and thunderstorms to South Texas and northern Mexico toward the middle of the week.
In the central and eastern Atlantic, there are a few clusters of thunderstorms that need to be monitored, but at this point there is no big concern for development.
