7 a.m. update
The National Weather Service has issued flood warnings for several rivers and streams across the region as rain-swollen banks continue to be impacted by scattered showers today. Impacts from the disturbance continue to include locally heavy rainfall, breezy conditions along the coast, elevated tides and marine hazards. The center of the system should push northwest throughout the day. The highest rain chances through noon should be along and west of the Brazos River. Those rain chances will expand across the area later today.5 a.m. update
The disturbance in the Gulf moved inland near Port Lavaca, and the National Hurricane Center doesn’t expect any more development. Locally, our impacts remain unchanged from prior updates, scattered showers and storms with breezy 30-40mph wind gusts possible, especially along the coast. The NWS has issued a Coastal Flood Warning through 7 a.m. for our coastal communities.
In a much different part of the world, northeast of Bermuda, we now have our first named storm: Subtropical Storm Ana has formed. This storm will have no direct impact on land, and is only notable for being our first named storm of the year, arriving before hurricane season officially begins.
1 p.m. update
The NHC is now giving the disturbance in the Gulf a 30% chance of development (becoming a Tropical Depression or Tropical Storm).
The impacts in our area will be minor regardless of development. We can expect scattered showers and storms along with wind gusts over 30 mph overnight and through Saturday, with rain tapering off from east to west on Sunday.
Still, if it makes landfall in Texas at tropical depression or storm strength, it’ll be the first in recorded history to do so before June 1, the customary start of the Atlantic hurricane season.
1 p.m. update
A large area of thunderstorms in the western Gulf is drifting northwest towards the Texas coast.
Conditions are slightly favorable for development and the National Hurricane Center is giving it a 60% chance. Whether it develops or not, it’ll give us at least scattered, heavy downpours overnight and through the day on Saturday.
High rain rates along with the slow movement of the storms means some flooding will be possible. Gusty winds and coastal flooding may also be an issue near the coast.
May 20, 2021
According to the latest NOAA outlook, the 2021 Atlantic hurricane season will be busier than normal, but it’s unlikely to be as crazy as 2020’s record-shattering year.They’re expecting 13-20 tropical storms, 6-10 hurricanes, and 3-5 major hurricanes.
Hurricane season runs from June 1 through November 30, although storms can form before and after those dates.
