Hurricane Isaias is pounding the Bahamas today with torrential rain and powerful winds as it passes through the Caribbean toward Florida’s East Coast. Isaias is expected to impact the Floridian coastline this weekend with a near-miss or landfall before making a possible second landfall in North Carolina on Monday. Isaias is the ninth named storm of the 2020 hurricane season – the earliest “I” storm on record – but the first to pose a significant threat to large portions of the East Coast. As of 5pm Friday Isaias is a low-end Category 1 Hurricane with maximum sustained winds of 75 mph located over the southeastern Bahamas. The hurricane is drenching the Bahamas with torrential rainfall capable of producing dangerous flash-floods as it begins aiming for Florida on Saturday and Sunday. Leading outer bands could work there way into southeast Florida as soon as late Friday night. The track of Isaias…

The entire Eastern Seaboard is on high alert for the first time during this hyperactive hurricane season as Tropical Storm Isaias bears down on the Caribbean, with increasing potential for a Southeast US landfall. Isaias is expected to approach the Florida peninsula this weekend and could bring tropical impacts from Miami to Cape Cod. Isaias was drenching Puerto Rico, Hispaniola (the Dominican Republic and Haiti), and the Virgin Islands with wind-whipped rain bands early Thursday afternoon. The system had maximum sustained winds of 60 mph and was producing tropical storm-force winds as far as 310 mi north from its center just southeast of the Dominican Republic coast. The storm was moving west-northwestward at roughly 20 mph toward Hispaniola’s mountainous terrain. Before Isaias approaches the US coastline it must confront two significant impediments to both its intensity and its track. The mountains of Hispaniola will quite literally be the most colossal…

Tropical trouble is brewing off the South Carolina coastline as thunderstorms organize around a developing low pressure. The system could produce torrential rainfall for the East Coast, with particular focus over the Northeast. Invest 98L, the low pressure system that the National Hurricane Center has given a 70% chance of becoming a tropical depression by Friday, only just crossed into the ocean Wednesday morning. With balmy sea-surface temperatures (SSTs) in the low-mid 80s°F (upper 20s°C) off the Carolina coastline, the developing low has plenty of fuel to intensify into a Tropical Depression or possibly, Tropical Storm. However, it will only have a brief window to reach Tropical Storm intensity. The low is expected to reach the Delmarva coast Thursday evening, where SSTs are in the mid-70s°F (mid 20s°C). These temperatures are too cool to sustain tropical cyclone growth. Contoured Sea Surface Temperature (SST) Map as observed by a global ensemble…
