Marine Weather and Tides
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
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.

UPDATE. Updated for 12Z aviation discussion
AVIATION. 12Z TAF discussion: LIFR cigs for the next couple hours in the east and southeast. Should be breaking up shortly after sunrise, then a return to VFR. Afternoon showers and thunderstorms again today, better chances for HBG/PIB, and forecast is reflective of that. Generally light and variable winds. Amount and location of better precip tonight will end up impacting the forecast after 06z tonight with LIFR cigs/vis, more than likely in the southeast. But so far, there is enough of a migration to the west in the pops that will be holding off on making that switch.
DISCUSSION. Today and tonight . Continued hot and humid conditions across the region will result in another Heat Advisory for today for much of Central MS and the ArkLaMiss region. General light flow over the region does little to advect anything to alter the airmass. Above normal temps continue as well with the region on the edge of mid level ridging parked over the desert SW. MaxTs continue to climb into the mid to upper 90s. Dewpoints in the 70s/approaching 80 push heat indices into the 105- 110F range. Mid/upper level ridging building in the models, providing a modicum of suppression for the convective element this afternoon, at least across the north/northwest. Plenty of instability, more than adequate llvl lapse rates . less so in the midlevels, but that was enough yesterday. Similarly, a lack of significant flow aloft would likely result in some slow moving storms and increased flooding potential. Some guidance seems to be focusing in the southeast, but the more recent model runs are tracking that same weakness/wave that has been the remnant of recent convection into the southwest as the afternoon wears on. As a result, have made some adjustments to the pops, backing likely tsra into the SW later this afternoon/evening.
Friday through Wednesday:
Summer continues across the South this weekend and into early next week. A broad ridge of high pressure aloft will become stretched out across the Interstate 40 corridor from Arizona and New Mexico eastward to the Carolinas. This will have the effect of shifting the axis of greatest heating generally to the north for the weekend and early next week. Max heat index values in our forecast area could still reach the 106 to 110 degree range on Friday, but slightly lower dewpoints on Saturday and Sunday may be enough to cap out heat index values closer to the 100-105 degree range across the area. Therefore will keep an "Elevated" heat threat mentioned in the Hazardous Weather Outlook text and graphics for Friday, extend the "Limited" threat into Saturday and Sunday, particularly for the ArkLaMiss Delta region. Heat Advisories may be needed over the next few days, and anyone with outdoor plans should continue to exercise caution and plan accordingly to stay cool and hydrated.
As the ridge lifts northward, the Gulf Coast region will come under the influence of the Easterlies, and a few waves are expected to move across the region through the early parts of next week. This would favor greatest diurnal shower and thunderstorm chances to be mainly south of Interstate 20 each day, but shortwaves moving through the westerlies north of the ridge axis could also steer some showers and storms toward northern parts of the forecast area at times. Model guidance suggests a weakness could develop in the ridge to our west by around Tuesday or Wednesday, and it's during that time frame that easterly waves crossing the Gulf Coast and a shortwave or two in the westerlies look to excite the rain chances again after a relative minimum over the weekend. Any severe threat will be conditional on parameters aligning for microbursts, but at this point in time there is no confidence in any organized severe weather threat. /NF/

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.
