Forecast Discussion

Space Launch Delta 45

Weak onshore flow is expected across the Space Coast today as we transition to drier conditions over the next couple of days. Elsewhere, Hurricane Fiona will continue to churn northwards towards Bermuda, creating a large area of elevated seas from Florida to North Carolina. On Friday, Fiona is forecast to accelerate northeastward as it passes Bermuda, keeping waves elevated from Florida northwards. A trailing band of convergence from Fiona is likely to develop when the pressure gradient intensifies as high pressure builds along the eastern US. As this band works its way into the area, it will produce elevated winds as well as squally showers along the Space Coast. The trailing convergence band should push south of the Spaceport Saturday as high pressure builds in, allowing winds and waves to diminish. The primary weather concerns for Saturday evening are the Cumulus Cloud Rule and Liftoff Winds. On Sunday, the pressure gradient relaxes, leaving the Spaceport in light easterly flow. This should provide more favorable launch conditions by evening, with only a lingering concern for the Cumulus Cloud Rule.
