First Alert Tropical Update: Invest 90-L may become first tropical system of the season

SAVANNAH, GA (WTOC) - Invest 90-L continues to produce showers and thunderstorms over the western Caribbean. The area of low pressure is near the Gulf of Honduras, just east of the Yucatan Peninsula.

This area of storminess has a 0-percent-chance of tropical development within the next 48-hours, but a 60-percent-chance of tropical development within the next five days.

Invest 90-L lifts northward, into the Gulf of Mexico, through the rest of the work-week. It is there that conditions will become more favorable for tropical development between Friday and Sunday.

Whether it develops into our first tropical system of the Atlantic Hurricane Season or not, it's going to send a lot of moisture into the Gulf Coast and portions of the southeast this holiday weekend.

A very wet period of weather is expected along the I-10 corridor from New Orleans to Panama City, Florida. Heavier rains spread further inland as time goes on. Even the I-20 corridor between Jackson and Atlanta will see some heavy rain.

Moisture from whatever comes of Invest 90-L will also increase our chance of rain – particularly Sunday into Memorial Day on Monday.

The main difference from the past few days:

  • Rain may be more widespread, longer-lasting
  • Locally heavy rainfall totals could be more widespread
