Tropical Storm Philippe (2017)

[1] On October 22, the National Hurricane Center (NHC) began to note the possibility of tropical cyclogenesis over the southwestern Caribbean Sea.

[2] The disturbance reached the southwestern Caribbean by October 24, where it interacted with the Central American Gyre, developing a broad area of low pressure the following day just offshore Nicaragua.

[1] Late that day, the NHC designated the disturbance as Potential Tropical Cyclone Eighteen, while it was located roughly 415 miles (668 km) south-southwest of Havana, Cuba.

[3] Although, at 12:00 UTC the next day, satellite imagery and reconnaissance aircraft data displayed a well-defined center, prompting the upgraded of Eighteen to a tropical depression, about 100 miles (160 km) south-southwest of Isla de la Juventud.

[4] The depression also shifted towards the northeast due to a mid-latitude trough that moved into the Southeastern United States and western Gulf of Mexico.

By 18:00 UTC that same day, the depression strengthened into Tropical Storm Philippe while just southeast of Isla de la Juventud.

This combined with strong southwesterly wind shear caused Phillipe to quickly weaken to a tropical depression by 00:00 UTC on October 29 before dissipating shortly thereafter.

[1] Potential Tropical Cyclone Eighteen, and its precursor which paralleled the coast of Central America, brought heavy rainfall to Nicaragua and Honduras.

[10] Ahead of Philippe, a Tropical Storm Watch was put in effect from Craig Key to Golden Beach in South Florida, at 15:00 UTC on October 28.

[13] Initially, Philippe was thought to have made landfall in Florida, although it was later revealed in the post-season analysis that the storm had already dissipated, with its track being confused with a nearby area of low pressure.

The roof of a nearby bowling alley was also damaged, letting water pour into meeting and mechanical rooms, and shifting a dumpster behind the building.

A wind gust of 75 mph (121 km/h) was reported on the Forest Hill Community High School campus as the tornado moved into West Palm Beach, with a nearby street sign being blown down.

[27] Strong winds in Newtown downed utility lines and caused a tree to fall onto a house, severely damaging a garage.
