Tropical Storm Peter has formed in the tropical Atlantic. It has reached an organized circulation that meets the standard along with top wind speeds that are estimated to have reached 40 mph. Peter is not a well developed system at this time as the storm is fighting some hostile upper winds and dry air. The center of Peter’s circulation is forecast to pass north of the northeastern Caribbean islands Monday. On its projected path, the worst weather would stay well north of the islands, but there is added uncertainty in the forecast because the system is just developing.

The environment around Peter is forecast to continue to be marginal, so it is not expected to strengthen swiftly or significantly. By Tuesday, the upper-level winds are predicted to become more hostile as the steering currents weaken. Then mid to late week, the consensus of the forecast models is that a new steering regime will take over and deflect the system to the north well east of the Bahamas and Florida. Because of where the system is in the ocean, we have to keep an eye on it to be sure nothing goes wrong with the forecast . But as of now, there is no reason for concern.

Along with Peter, Tropical Depression Seventeen has formed out of the disturbance near Africa. The only land it is likely to affect is the Cabo Verde Islands as it drives north into a lot of dry air.

The National Hurricane Center is forecasting the depression to strengthen and become Tropical Storm Rose. Looking ahead, the conditions the storm is currently in is not likely to encourage development therefore the storm is not expected to last very long or get very strong.

Not too far from Seventeen, another disturbance is forecast to emerge from Africa. It looks like this one is farther south in the tropical-development zone. At this time, it is a bit too early to make predictions on its potential strength or intensity. 

The system that was Tropical Storm Odette is now a strong North Atlantic winter-type storm. There is some chance that it could drop down over warmer water and briefly become somewhat tropical again. 

For a while, we will be watching as the storms battle it out in the middle of the Atlantic as all these systems compete for space. If they all end up reasonably strong, they’ll interact in unpredictable ways, but for now it looks like all of the action will stay far away from land.
