If it could possibly muster a extra outlined heart of circulation and strengthen additional it might change into Dexter, the fourth named storm of the Atlantic hurricane season — a mark usually reached round mid-August.
If it does type, it might achieve this simply off the Gulf Coast — a reminder that storms usually tend to type within the heat, shallow water nearer to land in July.

However just a few respected forecast fashions are predicting a extra organized system, probably a tropical storm, within the Gulf by late week. The result might hinge on the system’s monitor. If it dips additional south and spends extra time over the Gulf it might change into stronger if it could possibly face up to the upper-level winds on its journey.
Even when it isn’t named, this technique will convey tropical downpours to Florida and components of the Gulf Coast over the following a number of days.

Heavy rain may very well be long-lasting as soon as it begins, presumably as quickly as Wednesday evening.
Flash flooding is the primary concern, particularly if rain bands repeatedly monitor over the identical areas which might occur if the system strikes slowly and lingers.

By Friday, the risk will increase to a Degree 3 of 4 for components of Louisiana together with Baton Rouge over fears that heavy rain might linger. A number of inches of rain are attainable within the worst-case situations.
It’s clear that heavy rain and flooding will threaten a lot of the north-central Gulf Coast, however precisely the place and the way a lot stay in query. It can all rely on how robust the system turns into, the place it tracks and how briskly it strikes – questions that may change into sorted within the subsequent couple of days.
