(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 ktbw 201332 afdtbw area forecast discussion national weather service tampa bay ruskin fl 932 am edt Tue aug 20 2019 Update Latest rap surface analysis shows high pressure from the western atlantic extending west across the northern peninsula and into the eastern gulf this morning with an east-southeast wind flow across the forecast area. Morning RAOB data shows increased moisture across the area with a pw of 1.82 inches. This moisture combined with daytime heating will support scattered to numerous shower and thunderstorm development along the sea breeze circulations during the afternoon with the east-southeast steering flow favoring the best coverage and highest rain chances (pops 60%) setting up along and to the west of the i-75 corridor during mid to late afternoon with the storms then ending or shifting west into the adjacent gulf waters during the evening hours. Similar to previous days locally heavy rainfall will be possible with the storms, and with the ground remaining quite saturated from recent rains localized flooding of low lying and poor drainage areas will be possible along with some additional rises on area rivers. In addition to the rain strong gusty winds and frequent lightning strikes will accompany the storms. Current forecast has a good handle on all of this so a morning update will not be required at this time. |

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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. |
