Tropical update: Quiet now, might change later

An area showing potential for tropical development will head east across the Florida Peninsula this week, bringing showers and thunderstorms to the Sunshine State.

We're closely monitoring an area of disorganized showers and thunderstorms located in the Gulf of Mexico that is currently interacting with favorable conditions for further organization.

While it's unlikely to get a name this week, conditions could become slightly more favorable for additional development as we head into the weekend. At the time of this update, there was a 20% chance of tropical cyclone formation over the next 7 days in the highlighted yellow area above.

Based on long-range models, there is a possibility that this system might be attempting to develop east of Florida, resembling the situation observed last weekend. While it is important to note that we're several days ahead, it is worth being aware of this potential risk.

During this time of the year, the southwest Atlantic is susceptible to tropical development due to the presence of residual energy from fronts or previous low-pressure systems. With favorable conditions such as warm waters and low wind shear, the potential for easy development exists, often resulting in rapid landfall.

Another important factor to consider in the formation of tropical systems is the Madden-Julian Oscillation (MJO). This global atmospheric oscillation influences weather patterns through its alternating sinking (clear conditions) and rising (increased clouds and storms) motion.

When the MJO exhibits sinking motion (i.e., yellow/red shading in the graphic above), the likelihood of tropical development decreases, whereas rising motion (blue shading) enhances the chances.

According to the forecast above, the MJO is anticipated to bring about rising motion, creating favorable conditions for the formation of tropical cyclones in the eastern Pacific, Caribbean, and southwestern Atlantic regions over the next 7 to 14 days.
