Discussion
The climatological peak of the Atlantic Basin tropical season comes in mid-September and this year is certainly holding true to form. Tropical Storm Gordon came ashore early yesterday in the vicinity of the Alabama/Mississippi border region and it is now well inland in the south-central US. While Gordon has been downgraded to tropical depression status, it is likely to combine with a frontal system and contribute to an extended swath of heavy rainfall in coming days. Meanwhile, Florence has intensified into major hurricane (category 3) status out over the central Atlantic. There is still a chance that Florence gets “captured” by an eastward-moving upper-level trough of low pressure this weekend over the north Atlantic, but odds favor it being “left behind”. If indeed Florence is not “captured” by the trough this weekend then strong and expanding high pressure ridging to the north early next week could very well steer it westward towards the US east coast. Any potential impact on the US east coast by Hurricane Florence would likely come during the middle or latter part of next week.
