08/30 Ryan’s “Active Weather” Wednesday Forecast
This afternoon was an active one for weather, as multiple tornado warnings were issued and damage was confirmed on the ground. Tornadoes associated with tropical systems are generally on the weaker side and short-lived, which was consistent with what we saw today, but the heavy rains continue to be one of the biggest threats. Pockets of heavy showers with rain rates as high as 4 inches/hour are still moving in discreet bands across the area, but a considerable amount of drier air has moved in has weakened the storm and pushed the bands farther apart. These showers and storms will continue through most of the night & even some into tomorrow afternoon, but we’re nearing the end of Harvey, and it couldn’t come soon enough for many in SE Texas and Western Louisiana.
Harvey will continue moving inland and will weaken rapidly, expected to become a “remnant Low” over the next 72 hours. Rainfall totals as high as 3-6″ are still possible for parts of LA/MS as it continues slowly NE.
Tropical Storm Irma formed earlier today, and is expected to ride the outer edge of a high in place over the Eastern Atlantic over the next few days, pushing it further West and South. This storm is expected to slowly intensify in strength over the next several days, likely reaching Category 2 status by Monday as it approaches the Leeward Islands.
Other tropical formations zones are active as well! A broad and disorganized area of low pressure is slowly moving Northward from the Bay of Campeche, and currently has a 20% chance of forming into a tropical system by the weekend. The least it could do is bring heavy rains to the already devastated areas of Southeastern Texas and parts of Louisiana, but if it forms into a fully fledged tropical system, it could do considerably more as it moves towards the Gulf Coast.
