Cobb County in flash flood watch through Tuesday evening

More soggy news from the National Weather Service, which has issued another flash flood watch Monday afternoon to include Cobb County through Tuesday evening.

We’re expecting between 2-4 inches that started late Monday afternoon, and the rains aren’t expected to let up for the next day or so.

There’s a 100 percent chance of rain Monday night, and a 90 percent chance through most of the day Tuesday. The chance of rain is expected to taper off to a 60 percent chance Tuesday night, and up to 70 percent again on Wednesday night and into Thursday morning.

The watch area covers most of north Georgia, which was drenched by rain last week that led to flooding in some parts, including a few streets in East Cobb, as well as East Cobb Park, Sandy Plains Park and Noonday Creek Park. A part of Keheley Road remains closed north of Shallowford Road.

Tuesday’s high temperature is expected to be in the mid 50s, with lows around the same. The highs for Wednesday is forecast for the mid 60s, and likewise for Thursday.

Sunny weather is expected by Friday, but it’s going to get colder, only into the high 40s.

Cobb included in flash flood watch until Friday morning

Cobb flash flood watch

As rain moves into Cobb County and metro Atlanta Wednesday night, weather forecasters are saying enough will be coming to warrant a flash flood watch.

The National Weather Service in Peachtree City says the watch period will start at 6 p.m. Wednesday and continue through 7 a.m. Friday for north and much of middle Georgia.

Cobb is located in a line that could get between 3 and 4 inches during that time. Heavy rains are expected to start Wednesday night, up to six inches in some parts.

A 100 percent chance of rain Wednesday night is in the forecast, and a 100 percent chance is expected on Thursday. Temperatures will be warm, with highs in the mid to high 60s, but with a chance of rain at 80 percent later on Thursday and down to 40 percent as weather gets much colder.

Thursday night’s lows are projected to be in the high 30s, and while sunny, clear skies are forecast for Friday, the highs are forecast to be only in the mid 40s. Friday night will be clear with lows near freezing.

Rain and warmer weather are on tap for the weekend, with sunny skies and highs in the high 50s in the forecast for Sunday.

Cobb included in flash flood watch due to Alberto until Wednesday morning

Cobb flash flood watch, subtropical storm Alberto

The National Weather Service has included Cobb County in a flash flood watch until Wednesday morning due to rains stemming from Subtropical Storm Alberto.

The watch was to begin at 2 p.m. Monday and covers most of north and central Georgia. The heavy rains could cause flooding in rivers, lakes, streams and other low-lying areas.

Alberto was making landfall on the northwest Florida Gulf Coast early Monday afternoon, according to the NWS, which also included this information in its watch alert:

Subtropical storm Alberto will continue northward into eastern Alabama through this evening bringing abundant moisture and rainfall along and east of its track. This will allow for increased rainfall potential across the area. Although average rainfall totals will average 2 to 3 inches, some areas could see as much as 4 to 5 inches through Tuesday night. Creek and river levels are already above average and will not take much additional rainfall to cause levels to rise above bankfull.

Several creeks and rivers will rise out of their banks closing roads and impacting homes, businesses and farms. High water may not recede until well after the rain has ended.

The chance of rain in Cobb and metro Atlanta is expected to increase later on Monday afternoon and overnight and through Tuesday, possibly up to a 90 percent chance. We could get up to three-quarters of an inch of rain Tuesday night.

In addition to the rain and possible flash floods, foggy conditions may also be present.

The watch period ends at 8 a.m. Wednesday.

On Wednesday, thunderstorms are likely, especially on Wednesday evening, with the chance of storms tapering off as the week continues.

High temperatures Monday and Tuesday will be in the high 70s and lows in the high 60s. From Wednesday through Thursdays, highs could reach into the mid-to-high 80s with lows in the low 70s.

Sunny skies are not expected to return until Saturday.

Cobb flash flood watch in effect through Saturday morning; a rainy Memorial Day holiday weekend expected

Cobb flash flood watch, National Weather Service

Intermittent rainshowers are expected throughout the Memorial Day weekend, and to start it off Cobb and much of Georgia have been placed under a flash flood watch until 8 a.m. Saturday.

The National Weather Service said this afternoon the greatest chance for flash flooding is in central Georgia, along with portions of north Georgia.

Between an inch and two inches of rain could fall in those areas until Saturday morning. Localized flash flooding of creeks and streams is possible in places where heavy rainfall occurs.

This is from the NWS watch issued at 3 p.m. Friday:

“Additional rounds of very heavy rainfall are likely as a trough of low pressure to the west feeds very high amounts of moisture into the area. Widespread rainfall amounts of one to two inches are likely. Locally higher amounts of 3 inches or more are possible where storms repeatedly move.

“Much of this heavy rain could fall in a short amount of time. With the heavy rain that has already fallen in the last 2 days, it will only take a relatively small amount of rainfall to cause significant flash flooding.

“Creeks and rivers will rise out of their banks closing roads or impacting homes, businesses and farms. Roads may become closed for extended periods of time. High water will not recede until well after the rain has ended.”

The extended hazardous weather outlook for Cobb continues through Memorial Day and Tuesday, with scattered to numerous showers and thunderstorms possible every day. Heavy rainfall could occur stemming from Tropical Storm Alberto, which is projected to hit the northwest Florida Gulf Coast on Monday.

That is the first named storm of the year, although the 2018 hurricane season doesn’t officially begin until next week.

High temperatures in Cobb and metro Atlanta are expected to reach or exceed 80 degrees every day over the holiday weekend, with expected lows in the mid-to-high 60s.

After Friday’s 50 percent chance of rain, the chance of rain on Saturday and Sunday is forecast to be 60 percent, and around 50 percent on Monday.

Rain also is in the forecast for all of next week.
