Track of TS 10L

At 7:00 PM CDT (00:00 UTC), the center of Tropical Depression Hermine (10L) was located near latitude 31.1 North, longitude 99.4 West.

In the main image, a small portion of convection that is part of TD 10L can be observed along the right edge. The full system can be seen in the animated image.

Hermine is moving toward the north-northwest near 20 mph (33 km/hr). A turn to the north and then north-northeast is expected over the next couple of days.

Maximum sustained winds have decreased to near 35 mph (55 km/hr) with higher gusts. Continued weakening is forecast as Hermine moves farther inland over central Texas. Estimated minimum central pressure is 1003 mb (29.62 inches).

Hazards affecting land include storm surges, rainfall and tornados. Water levels along the Texas coast will gradually recede but remain above normal for the next day or so.

Hermine is expected to produce total rainfall accumulations of 4 to 6 inches, with possible isolated maximum amounts of 10 inches, from the middle Texas coast northward through central Texas and over central and eastern Oklahoma.

These rains are expected to spread northeastward across southeastern Kansas and Missouri during the next few days. The heavy rainfall could cause life-threatening flash floods. Isolated tornadoes are also possible over portions of central and southeast Texas this evening.
