Marine Weather and Tides
Version 3.4 |
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. |

AVIATION. One lone remaining shra from earlier precip to our nw looks to be dissipating across western Harris Co. Can't rule out an isolated shra at some of the metro airports, but not planning to include the mention in the 6z TAF package due to low impacts even if a few do form. The latest hires guidance shows the possibility of sct convection developing across parts of the region late Tue afternoon as temps climb above 93F or so (20-24z). Localized strong wind gusts will be the primary issue in/near any stronger cells. Otherwise, outside of any convection, VFR conditions are anticipated thru the TAF period. 47

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. |
