Pressure and weather in Port St. Lucie
Port St. Lucie sprawls inland from the Indian River Lagoon along the North Fork of the St. Lucie River, on flat ground fifteen to thirty feet above sea level, roughly midway between Palm Beach and Vero Beach. Its position on the Atlantic side of the peninsula places it in the path of systems approaching from the east and southeast, and the Treasure Coast took its name from Spanish treasure fleets wrecked along this shore by a 1715 hurricane, which is a fair indication of how directly it faces the Atlantic basin's main track. In 2004 Frances and Jeanne came ashore within three weeks of each other at almost the same point just south of here, and that pair remains the local reference for what a single season can do. Tropical systems produce the deepest and longest falls on the record, developing across days rather than hours and giving unusually generous warning. Outside the season the summer routine is sea-breeze convection, with the east coast breeze pushing inland each afternoon and storms firing where it meets the westerly flow, while the barometer stays nearly flat apart from the twice-daily tidal wobble. The Gulf Stream runs close offshore, keeping winter nights mild along the lagoon, and the few strong cold fronts that reach this far south arrive with a sharp northwest wind shift and a day or two of remarkably dry air.
What this means for you
Tropical systems announce themselves in the pressure trace days ahead, which is more warning than any other weather here gives. Using a migraine tracker app across a storm approach shows how early the fall actually begins.
