Update 4:05 p.m.: The National Hurricane Center canceled the hurricane hunter flight into former tropical depression 4 as the system became less organized.
Higher rain chances are still expected Thursday, with up to two inches possible in isolated spots, as the remnants of the depression move across South Florida.
The tropical wave several hundred miles west of the Cabo Verde Islands has fizzled with no chance of development, according to National Hurricane Center forecasters as of the 8 a.m. outlook.
But an Air Force hurricane hunter is still scheduled to investigate the remnants of tropical depression 4 today that technically dissipated last week but made an effort to reform Monday. Those plans may change throughout the day depending on the showery mass, which is north of Puerto Rico this morning.
While no tropical development is expected over the next 5 days, the former TD4 is expected to bring rain to South Florida later this week.
Rain — up to 2 inches in isolated spots — will be welcomed by parched lawns and humans weary of a 17-day stretch of 90-degree-plus temperatures measured at Palm Beach International Airport. The daytime highs, and warm overnights, are running above average, continuing a trend of abnormal heat felt statewide during the first half of 2017.
Although June ended with nearly double the amount of rain that’s normal for South Florida, coastal Palm Beach County is down 1.02 inches for July. Crouch said the statewide drought that ended in June contributed to the warmer-than-normal temperatures for the first six months.
That’s partly because instead of the sun’s energy working to evaporate water in the soil, it goes wholly to increasing temperatures.
Alyson Hoegg, a meteorologist with the Pennsylvania-based AccuWeather, said some areas of South Florida could get up to 2 inches of rain with the showers forecast to begin overnight Wednesday and through Thursday.
The rain is associated with the tropical depression the hurricane center was tracking last week. It dissipated Friday, but forecasters reopened the system as Invest 94L Monday after it showed signs of development.
Declaring a disturbance an invest (short for investigation), allows the hurricane center to get more detailed computer information on a system. An Air Force hurricane hunter is scheduled to make a trip into the system today.
Hoegg doesn’t think the disturbance will have time to regroup as it moves toward Florida, but said the hurricane center doesn’t want anyone caught off guard with something forming near the coast.
“There has been some model discrepancy, but it’s running out of time and we think there is a very, very low chance of it even becoming a depression,” Hoegg said. “I think the rain will be more widespread than on a typical summer afternoon in Florida and it may not be until Friday that some drier air comes through.”
