(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus64 klix 232109 afdlix area forecast discussion national weather service new orleans la 409 pm cdt Fri aug 23 2019 Short term More rain is expected across the region this weekend. A broad low over northwest gulf of mexico will continue to move north bringing deep tropical moisture over the area. That is moving north. This has already brought a surge of deep tropical moisture into southeast louisiana and south mississippi with precipitable water (pw) values running in the 2 to 2.3 inch range. This moisture will remain in place through the weekend and into Monday. The weather prediction center maintains a marginal risk of excessive rainfall along the coast this evening. For Saturday, a small portion of the coast will be in a slight risk of excessive rainfall and other areas in a marginal risk. Heavy rainfall will be possible with any convection over the next few days. The potential for banded storms and training storms over areas that have saturated soils pose a greater risk for flash flooding. A shortwave will be moving southeast from the central and southern plains into the lower mississippi valley Sunday and this should help pull this disturbance over the immediate forecast area. This will maintain deep tropical moisture and a favorable environment for fairly widespread rainfall and a threat of locally heavy rainfall. The entire forecast area is in a marginal risk of excessive rainfall on Sunday and Sunday night. We will have to watch to see if the risk areas are updated or expanded for Sunday, and also will have to watch to see if they could be extended into Monday especially across the eastern portions of the area. Long term A wet pattern continues into next week. Afternoon convection will continue each day. A frontal boundary will start to approach the region from the north. This should serve to trigger more convection during this time period. Guidance suggests that the boundary will get through the area. We will have to monitor the forecast for changes. Just expect temperatures to not be as hot with increased rain chances. Aviation Expect showers to diminish over the next few hours across the area. Expect mostly MVFR toVFR conditions to prevail overnight into Saturday. Afternoon convection will once again play a role in the forecast as more widespread coverage for Saturday is expected. Marine No significant changes to the forecast this afternoon which is basically light onshore winds and low seas outside of convection. |
The air mass will become increasingly more conducive for tropical funnel and waterspout formation in the near shore waters, near shore marshes and tidal lakes bays through the weekend. Expect nocturnal convection each night over the waters through next week. Decision support Dss code: yellow. Deployed: none. Activation: none. Activities: marginal risk excessive rainfall Sunday.

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. |
