Through 900 PM, a large cluster of showers and storms will drop south from southern Osceola County across Okeechobee County and the Lake Okeechobee area. Expect torrential downpours to produce rainfall amounts between 1 and 2 inches in a 60 to 90 minute period, along with occasional cloud to ground lighting strikes. The adjacent far western sections of Indian River, Saint Lucie and Martin Counties may also be brushed by a few of these showers or storms.
Scattered storms across northern Brevard county will produce locally heavy rain, gusty winds and cloud to ground lightning through late afternoon. Additional showers and lightning storms will develop as the east coast sea breeze moves inland and interacts with thunderstorm outflow boundaries from eastern Orange into Osceola and portions of southern Brevard and inland Indian River county. Other isolated storms will develop over the interior through late afternoon and early evening and be slow moving.
Scattered showers and thunderstorms will develop from Southeast Volusia County to Martin County along the east coast sea breeze boundary as it moves slowly inland. Additional showers and storms are expected to develop into Seminole, Orange, and Osceola counties through mid afternoon. Locally heavy rain, gusty winds, and cloud to ground lightning strikes will be possible with storms this afternoon. Stronger storms may develop late in the afternoon across Lake County as the east and west coast sea breeze boundaries converge.
Scattered lightning storms are expected to develop along east coast sea breeze by early afternoon from Brevard to Martin county and move slowly northward as the east coast sea breeze pushes inland. Locally heavy rainfall amounts of one to two inches, gusty winds and lightning can be expected with the initial activity. Stronger storms may develop by mid to late afternoon as the east coast sea breeze pushes into the interior.
