Sunday forecast:

HOUSTON – Tropical Nicholas formed this morning and that means big weather changes for today and into this evening. Moisture levels are creeping back up.

As of this writing the forecast is for the storm to remain as a Tropical storm with winds just under Category one status. Expect sustained winds of 35-45mph with gusts up to 55mph. Heavy rain will be a big part of this system as it takes the next two to three days to move up the coast and into and through the Houston area. A Flash Flood Watch has been issued from 7pm Sunday until Tuesday evening. As of right now the forecast is for 5-10 inches of rain across the region with isolated amounts of up to 15 inches in some areas.
