System upgraded to tropical storm


With the formation of a more well-defined surface circulation moving inland into coastal Brazoria County there is slightly more confidence in the rainfall forecast and amounts.

It appears that the center of Imelda will continue to move N to NNW along/near SH 288 through Brazoria County and then into Harris County this evening and overnight. Heavy rainfall looks to concentrate near the center and in banding features to the right (east of the center) and this will effect areas along and east of the SH 288 and I-45 corridors

Widespread rainfall amounts of 4-7 inches with isolated amounts of 10-15 inches will be possible along and to the east of the track of the center of Imelda this evening into Wednesday.

With the potential for more concentrated rainfall near the inland moving center and banding features on the east side to increase the hourly rainfall rates, rises on area bayous and creeks can be expected this evening and overnight.
