TYLER, TX (KLTV) - Yesterday we brought to everyone's attention there could be a tropical system developing near Cuba. The National Hurricane Center had this area under a slight risk of developing but we mentioned the system looked fairly organized and was worth monitoring closely. This morning it is now looking likely this system will develop into a tropical depression later today and possibly Tropical Storm Don. The National Hurricane Center now has this area under a high likelihood of development and is sending an air force hurricane hunter to investigate. Once the plane reaches this system I have a good feeling it will be classified as a depression.
Now for the good news. It appears the timing of this system along with the eastward movement of our strong high pressure that has been baking us all summer will allow for lots of tropical moisture to invade the area. So even if what could become Don moves to our south, the chances of seeing afternoon thunderstorms will increase greatly Friday and Saturday and should bring an end to the streak of 100 degree days.
It is not all good news however. If this system moves farther north that could put East Texas in the area we would need to monitor for weak tornadoes that occur with land falling tropical systems. Also, with the extremely dry ground, rapid run off could occur with very heavy downpours giving parts of East Texas a threat of flash flooding.
