July 21: Tropical Activity Detected

Tropical Depression 2 has formed in the Atlantic Ocean. Dry air from the Sahara Desert has hindered development but enough energy has escaped to set a course for the Lesser Antilles. That seems to be the modeled direction for the next 3-4 days. After that the track is uncertain but a good point of reference is the Haiti/Dominican Republic region. When a storm passes north of that, it normally means a curve north towards the east coast. A pass south of that area will almost always end up heading straight into the Gulf of Mexico. Here’s the NWS National Hurricane Center’s current projected path:

Here’s also some blended tropical model guidance (also known as a spaghetti plot) indicating a solid consensus for Lesser Antilles impact as a tropical depression:

So it looks like we have some tracking to do over the next few days. This storm is still only a tropical depression but further development is expected. Maximum impact to the Lesser Antilles would be tropical storm intensity early next week. At this point it’s on our radar until it either fizzles out or misses. Be safe! JC
