LATEST ON TROPICAL STORM IDA

Ida has now been downgraded to a tropical depression but continues to look very healthy on radar as abundant rainfall is fed into the storm from the Gulf of Mexico. Further weakening is expected as it moves inland.

Tropical Outlook

TUESDAY

Tuesday will be the day to prepare. Much of the day will remain dry with only isolated to scattered showers and storms. A few of the rain bands from Ida may try to move in late Tuesday evening. Clouds will fill back in with highs in the upper 80s. Any storms Tuesday may produce intense downpours.

WEDNESDAY

Ida’s remnants enter the area from the west around sunrise Wednesday inching its way east through the day before exiting late Wednesday night.

The National Weather Service has issued a Flash Flood Watch from Tuesday afternoon into Wednesday night. Excessive rainfall of 2-4″ is likely and some locations could see 3-5″ of rain in any storms. Lower amounts are expected to the east toward Central/Southside VA.
