Tropical Depression Two is forecast to become a Tropical Storm later today as it slowly drifts northwest towards the north-central Gulf today and tomorrow before turning more to the west. Minor impacts are possible for marine and coastal areas, including gusty winds, coastal flooding/storm surge, hazardous marine conditions, and heavy rainfall. Continue to monitor the forecast for changes.
Given the last few days have already been on the toasty side and impacts from heat are an accumulating issue the heatrisk is increasing across the area. The heatrisk increases across the region given it will continue to be very hot and this doesn't look to change going through the first half of next week. One thing to be aware of, minaly for people along the coast who could have the greatest impact, if you are making preparations for the tropical system tomorrow be congizant of the heat and make sure to not become a heat casualty.
