Isaias is the first storm in the Atlantic this year to reach hurricane status. El Niño has kept the season relatively quiet.

Storm expected to reach 110 mph before weakening ahead of landfall late Friday or early Saturday.

Scenario 3: Tropical Storm Isaias forms, heads north and makes landfall on the Gulf Coast, bringing strong winds and storm surge on top of heavy rain. This scenario would be the most impactful outcome, although Isaias would still likely stay below hurricane strength.

While the DFW area continues to enjoy exceptional morning weather, Hurricane Isaias is strengthening in the Gulf and preparing to make landfall along the northern Gulf Coast.

While things might not be so calm in the Gulf with the formation of Hurricane Isaias, things are pretty pleasant in the Houston-area.

A weather system in the Gulf has developed into Tropical Depression Nine and may eventually strengthen into a hurricane as it moves toward the northern Gulf Coast.

The National Weather Service in Mobile continued to deal with trouble with its weather radar systems on Monday. The weather service said that technicians were still trying to fix the problem but there was no estimate on when the radars would be back to fully operational.

A system is expected to organize, with the National Hurricane Center giving it an 80% chance of becoming a tropical depression within the next two days and 80% within seven days.

Tuesday looks like it'll be pleasant when it comes to the weather. We are keeping an eye on Invest 92L in the Gulf as it has an increased chance of becoming a tropical depression or storm.

Tropical Storm Isaias formed in the southwest Gulf Wednesday morning. Hurricane and storm surge watches have been issued for parts of the central Gulf Coast.
