Marine Weather and Tides
Version 3.4 |
10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus64 klix 150921 afdlix area forecast discussion national weather service new orleans la 421 am cdt Tue oct 15 2019 Short term Warm front moving north very slowly this morning and will set up over central to southern miss today. This is where most of the sh TS activity will be found. Most areas north of the tidal lakes should get atleast a shower today while most areas to the south may not see a lot of activity. There is a chance of a strong thunderstorm as cells approach the warm front today but this should be mainly over the northern most tier of counties parishes. A new cold front currently over the northern and central plains will move southeast rapidly today forcing the activity along the warm front southward. The good thing is the upper support moves northeast causing the area to become more stable. But showers with some thunderstorms will still make their way south giving some rain to south shore locations overnight into Wed morning. The wind shift will move through the area with the line of sh TS which will be just before and around daylight wed. The cold front will lag just a bit and move through the area around and just after daylight. The line of sh TS will continue to become more stable as they approach the coast Wed and should decay as they move over the open gulf waters. Strong high pressure will then settle over the gulf coast. The cold front will stall over the northern gulf close to the coast. The area near the yucatan and bay of campeche this morning will begin to get funneled northward Thursday spreading out over the northwestern half of the gulf Friday. The high that will be over the gulf coast will keep the deep tropical moisture over the gulf until as early as Friday, and the moisture may move into the area slowly at first until return flow can get established on the back side of the high. The highest rainfall areas look to be anywhere from the central to eastern gulf coast by the end of the week. But there is still a lot of refining to do with this system. Models are having a tough time with it and would like to form a sfc low, but at the same time, westerlies and dry air wrapping in on the west side look to make things tough on the system. The systems presentation looks more hybrid but becoming more baroclinic as it approaches the coast. This is not going to be the focus though, instead impacts from this system could be several different forms depending on where the main plume of moisture comes ashore. Where this occurs, the impacts will likely be coastal flooding from high tide levels, flooding rainfall, and severe thunderstorms. By the start of next week, a new strong cold front moves into the area washing all this mess offshore. Aviation Ifr ceilings will persist through the early morning hours at kbtr and kmcb. Boundary layer mixing will increase enough by mid-morning to allow ceilings to improve to around 2000 feet and then further improve intoVFR conditions by the afternoon hours at these terminals. The remainder of the terminals should remain in vfr conditions through this evening. Some stratus build down is expected to occur tonight as a cold front moves through the area. Ceilings should decrease back into MVFR range of 1000 to 3000 feet. |
Pg Marine 10 to 15 knots winds will veer from the southeast to the southwest today into tonight. By tomorrow morning, a passing front should shift winds to the northwest. Colder air advecting from the north tomorrow night will increase winds into the 15 to 20 knot range. Seas will increase from 1 to 3 feet today and tonight to 3 to 5 feet by tomorrow night. Winds will gradually veer from the north to the east by the end of the week. A low pressure system passing through the gulf may push winds into advisory levels over the gulf waters from Friday afternoon through Saturday morning. Seas of 6 to 8 feet will also be possible as the low pressure system moves through the gulf on Friday night and Saturday. The low should push away from the area by Sunday, and a lighter southerly wind of 10 to 15 knots is expected to develop. Seas should also begin to decrease to 2 to 4 feet by Sunday evening.

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. |
