Local lightning, trouble in the tropics

Local lightning, major trouble in the tropics (IMG:WPMI)

More rounds of rain, lightning and thunder are in the forecast through Friday as our summertime pattern persists. They will be hit-and-miss storms with a few torrential downpours, mainly during the afternoons. The rain risk diminishes this weekend as drier, more stable air is pushed into our area by an upper-level high pressure ridge...and the wind flow pattern on the back side of hurricane Florence over the Carolinas.

Tropics:

Florence is a major category 4 hurricane on a crash course with the Carolinas. Thursday night is the most likely time frame for landfall along the North Carolina coast. Adding to the catastrophic potential is the flooding that will follow as the storm stalls out. Some areas could see 15-20" of rain and isolated amounts of 30" are not out of the question!

Hurricane Helene is a category 2 hurricane on the other side of the Atlantic will slowly weaken over the next few days as it heads north toward colder waters of the north Atlantic Ocean.

Isaac is a tropical storm and is moving west toward the Caribbean. Isaac will gradually weaken as it cruises through the Caribbean. However, as long as it is an organized tropical system in that area, we'll keep an eye on it.

We're also watching a cluster of showers and storms near Mexico's Yucatan peninsula. The National Hurricane Center gives it a 70% formation chance over the next 5 days. It most likely will continue heading west towards northern Mexico and the Texas Gulf Coast. At this time I don't see it being a threat to our part of the Gulf Coast.
