Area Forecast Discussion National Weather Service Melbourne FL 1017 PM EDT Thu Oct 22 2020

UPDATE. Very few, minor changes made to the forecast this evening, just to keep a mention of isolated showers along the coast through the overnight. A familiar pattern continues, with high pressure over the eastern US and Epsilon churning just east of Bermuda in the Atlantic. One difference this evening, however, is that the pressure gradient between these two features has begun to relax, lessening winds offshore and along the coast compared to previous days. Despite this, easterly flow will persist overnight, with PWATs 1.7 to nearly 2" supporting isolated showers pushing onshore into coastal areas. Like previous days, inland areas should remain mostly dry, especially after midnight. No thunder is expected and showers will continue moving at around 15mph, but brief downpours will be possible. Partly cloudy skies will continue, as lows fall into the low 70s for most of the area, with mid 70s along the Treasure Coast.

AVIATION. VFR conditions prevailing outside of precipitation. Showers continuing to push onshore through the overnight and have included VCSH at coastal terminals to account for this. Inland terminals should remain dry, as showers struggle to make it inland after midnight. Easterly flow continuing, with winds near or less than 10kts. Scattered showers and isolated storms expected again tomorrow afternoon.

MARINE. Hazardous boating conditions continue and a Small Craft Advisory remains in effect for all east central Florida Atlantic zones. The pressure gradient between high pressure over the eastern seaboard and distant Epsilon just east of Bermuda has begun to relax and easterly winds will finally diminish to 10-15kts overnight. Seas, however, will remain elevated, as swells from Epsilon reach the Atlantic coast. Seas up to 8 to 9 ft and pockets of 10ft, with long periods to end the week.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerous of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
