6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported. 5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive. 5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kmfl 212347 afdmfl area forecast discussion national weather service miami fl 747 pm edt Mon aug 21 2017 Update Quick update to adjust pops for tonight based on radar and satellite trends. Convection associated with the bahamian tropical wave has waned a bit the last few hours. This may be a diurnal minimum. With an increase in moisture still approaching, model trends support scattered additional convection developing overnight over the atlantic waters and approaching the southeast coast around sunrise. Otherwise no changes to the previous forecast. Aviation Scattered showers with brief MVFR or ifr conditions expected to affect fll mia area sites through about 03z, otherwise mainly dry andVFR will prevail for most of the night. Winds 060-080 degrees 10 knots or less all sites, shifting to 100-110 degrees 10-12 knots by 15z Tuesday as trough moves into area. Trough will introduce deeper moisture and increased showers across all of south florida during day on Tuesday, with prob30 for tsra MVFR brief ifr at all sites from 15z-18z onward. Prev discussion issued 357 pm edt Mon aug 21 2017 discussion... scattered cumulus clouds dot the south florida sky at mid afternoon as the eclipse comes to an end. The area is under a subsident regime between two tropical waves with a well-defined capping inversion on the mfl 12z sounding. Goes-16 imagery indicates the next tropical wave (called invest 92l by the national hurricane center) rapidly approaching from the east. In fact kamx 88d indicates scattered showers already beginning to cross the east coast. Tonight and Tuesday: coverage and intensity of showers and a few thunderstorms are expected to steadily increase tonight over the east coast. Activity may hold off til closer til sunrise near the collier gulf coast and glades hendry counties. High resolution guidance suggests convection that moves in will have the potential for efficient rain rates especially toward sunrise and during the day. Coverage increases Tuesday as the axis of the tropical wave moves over and then just northwest of the area and the region enters the more favorable sector for upward motion. Wednesday through Friday: the leftover vorticity associated with the tropical wave comes nearly to a halt over the area wed-thu. This will yield a deep southeasterly fetch tapping rich tropical moisture with several weak disturbances bringing periods of convection. Whether 92l develops a surface cyclone near the region is not the most important thing to focus on in terms of impacts. Regardless of the scientific classification of the system, the most significant impacts are likely to be from periods of heavy rain. This weekend: the trailing front from the canadian low gradually sinks into the southeast us and approaches northern florida. This front will likely absorb whatever vorticity remains of 92l just northeast of our region. This will keep southerly southwesterly |
flow with rich moisture overhead, favorable for continued periods of showers and thunderstorms with locally heavy rain. Impacts from heavy rain through the weekend: typically prone areas of poor drainage will be at increased risk of ponding water and occasional minor flooding. Areas of street flooding are also likely to be an issue during periods of heavy rain. While there is some risk for more significant flooding problems beyond the usual vulnerable roads and low spots, there is not enough confidence yet regarding timing location of the greatest threat to justify a flood watch. However, a watch may still be needed later in the week as the ground saturates. Marine... over the atlantic waters, a fresh easterly breeze today will gradually decrease Tuesday to gentle as winds turn out of the southeast, eventually swinging to southerly or southwesterly by the weekend. Over the gulf waters and lake okeechobee, a moderate easterly breeze tonight will become variable in both direction and speed from Tuesday into the weekend, but remaining generally below 15 knots. A moderate chop and seas to 4 feet tonight will gradually improve Tuesday into the latter half of the week. Periods of showers and thunderstorms can be expected tonight though the coming weekend, with locally gusty winds and higher waves near thunderstorms. Beach forecast... a moderate risk of rip currents will continue through the night at the atlantic beaches as moderate gusty onshore winds continue. The risk will gradually diminish back to slight levels Tuesday. Prev discussion... Issued 150 pm edt Mon aug 21 2017 aviation... vfr conditions will prevail through this evening. Winds this afternoon will be east around 15 kts gusting to 20-23 kts for east coast terminals. Tropical wave approaching from the east will bring vcsh tonight for east coast terminals. Increasing coverage of showers along with some thunder possible after 09z and continuing into Tuesday for east coast sites. MVFR conditions likely at times on Tuesday morning for east coast sites. Showers are unlikely to be near apf until after 15z. Future shifts will evaluate potential for tempo groups and possibly shra in prevailing.

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. |
