(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 ktbw 191328 afdtbw area forecast discussion national weather service tampa bay ruskin fl 928 am edt Mon aug 19 2019 Update Latest rap analysis shows surface high pressure from the western atlantic extending west across the north-central peninsula and into the eastern gulf with a light east-southeast wind flow across the forecast area. Morning RAOB data shows drier air over the region with a pw of 1.76 inches which is down over a quarter of an inch from yesterday at this time. This drier air will likely delay the onset of convection during the afternoon and will keep overall coverage lower than previous days, but am still expecting scattered showers storms to develop during the afternoon with the best coverage focusing along and east of the i-75 corridor late in the afternoon where the east west coast sea breeze merger will likely occur. A weak steering flow via RAOB data will support slow moving storms with some locally heavy rainfall likely. With the ground remaining quite saturated from the recent heavy rains some localized flooding of low lying and poor drainage areas will be possible along with some additional rises on area rivers. In addition will need to monitor the ongoing areal flooding across levy and citrus counties as well as local flooding along the little withlacoochee river in southwestern sumter county and east central hernando county where flood warnings remain in effect |
until 530 and 9 pm respectively. Current forecast is on track with no morning update required at this time. Aviation Will maintain vcts at all of the terminals between 20-01z for some late afternoon scattered shra tsra development, otherwise vfr will prevail. Light east winds this morning will become west northwest at 6 to 8 knots at the coastal sites after 19z as the sea breeze develops, with light east to southeast winds expected after 01z tonight. Marine East to southeast winds around 10 knots with seas of 2 feet or less will continue across the gulf waters the remainder of today with an onshore sea breeze component developing along the coast during the afternoon. Ongoing forecast is on track with no changes expected in the mid morning update around 10 am. Tbw watches warnings advisories Fl... None. Gulf waters... None.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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. |
