Updated 9:00 A.M. EDT Tuesday
Typical summertime weather has returned to the Panhandle and Big Bend. Skies are clear this morning turning partly cloudy by the afternoon. Scattered showers and thunderstorms will develop along the sea breeze during the afternoon, first along the coast and then moving inland. Rain chances will generally range from 40 to 60 percent. A pocket of dry air aloft will limit any rain chances in Northeast Florida today. For the southern half of the Peninsula, rain chances will be high today thanks to a tropical wave moving into the area. Scattered showers and thunderstorms are already ongoing across Southeast Florida and the Keys and will become more numerous during the day. Any thunderstorms could contain frequent lightning, heavy rainfall, and gusty winds. Localized rainfall amounts could top 1” in South Florida today which may cause minor flooding if in an urban or low-lying area. Highs will be in the upper 80s and low 90s statewide. However, the Heat Index or “Feels Like” temperatures will still reach the low 100s today for most.
Shower and thunderstorm activity will greatly decrease a couple of hours after sunset in the Panhandle and Big Bend. A stray shower remains possible overnight for coastal regions. Showers and isolated thunderstorms will continue in South Florida into the overnight hours. Temperatures tonight will range from the low 70s to low 80s statewide. Light, patchy fog is possible in the Big Bend near sunrise.
A moderate risk of rip currents is forecast for all Atlantic beaches. Onshore winds will be 10-15 mph with wave heights from 3-4’. Conditions will be calmer in the Gulf, with wave heights around 1-2’. A low risk of rip currents is forecast today at all other Florida beaches. Beach goers are urged to check with local beach rescue for the latest surf conditions and to always swim within sight of a lifeguard. Remember, rip currents can still occur on low risk days!
The remnants of Harvey are over the Yucatan Peninsula this morning, tracking northwest into the Bay of Campeche and southwest Gulf of Mexico. It has a 90% chance of redeveloping once it moves back over open water. This system is likely to impact northeastern Mexico and Texas later this week. This system will not directly impact Florida. Another tropical wave, Invest Area 92L, is over the western Bahamas this morning and is producing limiting showers and thunderstorms. Development is not expected, but increased rain chances are in the forecast for South Florida today and tomorrow. 92L has a 10% (low) chance of development during the next 48 hours, and a 30% (low) chance of developing in the next five days. If any development does occur, it is likely as the system pulls northeast away from Florida late week. For the latest information on the tropics, please visit hurricanes.gov.
