Most of the storm's winds will be on the east side of the center, but they will come close enough that forecasters decided watches are necessary.
Potential Tropical Cyclone 18, the 18th storm actively tracked by the hurricane center this year, is expected to reach tropical storm strength at some point on Saturday.
It's important to note regardless of Philippe's organization or further intensification in the next day, the impacts to Southwest Florida aren't expected to change.
Go to myfoxhurricane.com for continued updates on Phillipe's track throughout the weekend. But in between, a coastal storm is expected to bring plenty of tricks our way, complete with heavy rain, the potential for flooding, and strong wind gusts as well.
Tropical Storm Watches are in effect, as the brunt of the storm will stay off shore. If it becomes Philippe, the system would be the 2017 hurricane season's 16th named storm.
The Sun Sentinel reports that heavy rains have already hit South Florida.
Maximum sustained winds are near 35 miles per hour (55 km/h) with higher gusts.
"The forecast track of the center lies about 35 miles southeast of the Upper Florida Keys and extreme southeast Florida", NHC wrote in a statement on Twitter Saturday. This will steer the evolving tropical system northward across the northwestern Caribbean today and then over western Cuba tonight before emerge into the Florida Straits late tonight. It said the rainfall is spreading north across the Florida Keys and South Florida.
