Area Forecast Discussion National Weather Service New Orleans LA 337am CDT Sat Jun 21 2025 Long Term (Sunday night through Friday) Issued at 224am CDT Sat Jun 21 2025 We may not see any tropical cyclones at the moment, but we difinitely see tropical waves(easterly waves) moving over the area and one of these looks to move through Tuesday. These simply boost our precipitation chances and can be breezy when interacting with the Bermuda High. We will keep with the normal chances of sh/ts into the first of the week but lift those chances for Tuesday, and this may come in during the morning hours around sunrise, especially along the coast. After Tue, precipitation numbers fall again to a more normal value. With these deep moisture waves moving through, there is always a chance to see waterspouts approaching the shoreline. These are normally weak and land normally disrupts their circulation unless there are stronger upper level processes involved. But each summer a few manage to just cross the coast before dissipating and can cause some wind damage. Otherwise, the rain can be beneficial from time to time as the heat ramps up. Marine Issued at 224am CDT Sat Jun 21 2025 Easterly to southeasterly winds less than 15kt is expected throughout this fcast. There is a chance of sh/ts each day and night. Some of these could become strong causing winds to shift and rise abruptly. NOAA New Orleans LA Office: Watches - Warnings - Advisories LA...
