09/14 – Brantly’s “Heavy Rainfall” Tuesday Morning Forecast

It is not important to just focus on the eventual dissipation of any tropical cyclone. Some of the most damaging and life threatening variables can still be associated with it. Flooding rains and gusty conditions will still be an issue with this system as it creeps east hugging the I-10 corridor over the next few days.

Along the coast, the fetch over the Gulf will also increase along with wind speeds to around 15-25 kt and remain there for about 24 hours maybe a bit longer while we are in a spring tide cycle. This will be enough to bring up a Coastal Flood Advisory for some locations where tides will be around 1-2 ft above normal. As with any very slowly moving tropical system, rainfall amounts will be high and should be a common 5-10 inch storm totals along and south of the 1-10/1-12 corridor with isolated higher amounts. North of this area amounts are expected to be lower but still enough to bring a Flash Flood Watch for the entire area. And if any higher total rainfall values or if they shift slightly northward, this would become a problem for people in SW Mississippi as well. Heavy rain potential will be slow to move out and we could see this linger into Thursday.

Highs today will range from the lower to mid 80s.. Lows tonight will be in the upper 60s to lower 70s north of I-10 and in the lower to mid 70s south of I-10. Highs on Wednesday will then be cooler due to the increased chances for showers. Temperatures will range from the upper 70s to lower 80s area-wide.
