Central Florida is a Hurricane Magnet! How many of you have experienced one of these storms? It’s remarkable - almost hard to believe - that all these storms in the past ~20 years have passed right over the same area! I did a #hurricane talk in the Davenport/ Haines City/ Kissimmee area this week and I showed this graphic. When we think about hurricanes the coast always comes to mind, but inland areas have been very hit hard! So, the lesson is: no matter where you live in #Florida you must always be prepared. Hurricane season starts in 3 days.

Drought & dry conditions continue, keeping fire weather concerns elevated. ⚠️ Watch for a potential dry-cold front late weekend/early next week. It could bring higher fire danger. Please do your part to prevent new wildfires! 🔥 #FLwx #ALwx #GAwx

#Drought continues to worsen across #Florida despite recent rainfall. 73% of the state is in extreme drought and nearly 10% is now in the exceptional category. With the rainy season still a couple of months away, the wildfire threat across the state will remain elevated, making hyper-local weather data even more important. #floridaweather Contact us now to bring our state-of-the-art monitoring to your location: hubs.li/Q048rC6p0

Smoke is reducing visibility to near zero along Alligator Alley this afternoon from the National Wildfire in Collier county. Use extreme caution between MM 76 and MM 80. Southerly winds will continue to push smoke across the highway the rest of the day. #FLwx

Spotlight on Florida, which is dealing with its worst drought since at least the early 2000s. 67.4% is in Extreme Drought (D3), most D3 in FL in #DroughtMonitor history. Soil moisture and streamflows are low. Forecasts and outlooks lean dry. drought.gov/states/florida @NOAA @SERCC
The February 17 U.S. Drought Monitor highlights Florida, which is 98.8 percent in drought.

2/6 @ 8:30AM: As dry air continues to filter into South Florida in the wake of yesterday's frontal passage, the dual combo of (1) dry vegetation thanks to our longstanding drought & (2) low relative humidity could set the stage for enhanced fire behavior both today and tomorrow.

After recent record cold air outbreaks, SST anomalies around Florida show pockets near –5°C (~9°F below normal) along the coast, driven by persistent northerly winds cooling shallow waters. #FLwx

To say it's been dry across Lake Worth Florida is an understatement at this point. Quick summary of the last 76 days at my coop site just barley edged an inch 1.22 of measurable rainfall. #FLwx @NWSMiami @FLClimateCenter

There has been plenty of buzz about a strong cold front that is forecasted to arrive across South Florida during the early portion of next week. But when does it get "cold" in South Florida on average? And how have we matched up thus far this year? Here is a graphic for that:

If you like an erratic, and at times very cold pattern, you’ll love the expected Sudden Stratospheric warming event (SSW) later this month. While we can’t blame this (next week’s) cold air outbreak on the SSW, perhaps more to come in December as a result of it. We do have a more modest weakening now, and perhaps it’s contributing some to the amp’s pattern, but the bigger one seems to come in a couple of weeks.

Some bad news and not really shocking... the drought continues to worsen across the area. North Florida and South Georgia are under a severe to extreme drought. With little rain in the forecast, this will continue to become more of an issue for farmers. More on @WCTV at Noon...
