Tropical Storm Cristobal
June 7-8, 2020

 

Tropical Storm Cristobal was the 3rd named storm during the 2020 Atlantic Hurricane Season and the first storm of the season to impact the NWS Mobile/Pensacola county warning area in the 2020 season.

 

 

Summary of all Local Storm Reports (LSRs) across the area during Tropical Storm Cristobal and LSRs across the region during Cristobal.

 


Tropical Storm Cristobal made landfall west of our area, but significant impacts were felt across the entire region. The majority of this document will focus on the impacts from coastal flooding and wind across southeast Mississippi, southwest Alabama and northwest Florida. Below are some of the local impacts...

Interesting Hurricane Cristobal Related Stats

Cristobal is the earliest third named storm on record in the Atlantic Basin.



RAINFALL

Cristobal's angle of approach to our coastline put much of the area in a favorable location for very heavy rainfall. The highest rainfall amounts generally occurred across the southern and western portions of the area. The image below via the NWS and NWS Weather Prediction Center shows the cone overlaid on top of the predicted rainfall amounts ahead of landfall. Meanwhile, the loop of rainfall imagery to the right shows where the heavy rainfall fell each day, starting in northwest Florida on June 6th and migrating further west each day (note: thanks to NWS Birmingham for the state rainfall imagery).

The highest storm total rain of 10.33" occurred in West Mobile, AL. Widespread rainfall amounts of 7"+ fell across the southern portion of our area. Heavy rain in Mobile County resulted in some flooding across the county. A water rescue was made in Prichard due to a car being stranded in floodwaters. Although widespread flooding was not noted during Cristobal, the excessive rainfall brought a 1-2 category improvement in the drought. Along the local rivers, heavy rainfall led to rapid rises, especially along the flashier rivers. However, there were no major impacts along any rivers during this event.

A list of some of the higher rainfall totals can be found in the Post-Tropical Cyclone Report at the bottom of this webpage. A comprehensive list of rainfall totals across the area can be found on our dedicated rainfall webpage for Cristobal.

 


 


WIND

Wind gusts of 50+ mph were observed across much of the coast during Tropical Storm Cristobal with the strongest winds along the immediate coastline of Mobile Bay. The highest land-based wind gusts observed across the region were at Brookley Field in downtown Mobile with gusts to 56 mph late in the evening on June 7th. 

Across southwest Alabama, downed trees and power lines led to scattered power outages throughout Mobile and Baldwin Counties during Tropical Storm Cristobal. 

A list of the highest wind gusts (44+ mph) can be found in the table below.

The comprehensive list of land and marine wind gusts (converted to mph) can be found at this link.

 


COASTAL FLOODING

Coastal flooding was greatest on the eastern side of Tropical Storm Cristobal due to its angle of approach to the coast. High tide was completely out of phase with the time of the maximum coastal flooding, thus the majority of our coastline only experienced moderate to minor coastal flooding. If the highest water levels had corresponded with high tide, inundation would have been further amplified, especially across northern Mobile Bay. Below is a list of the peak inundation for all tidal gauges across the area during Cristobal.
 


The highest coastal flood levels across our area were observed in the northern portion of Mobile Bay, as seen in the Mobile State Docks and US Coast Guard Sector Mobile graphs at the bottom of this section. The highest inundation occurred after landfall on Monday, June 8th in northern Mobile Bay as the winds turned from easterly to southeasterly, which pushed more water into the northern reaches of the bay. Peak inundation was generally around 3-4 feet (moderate coastal flooding levels) in northern Mobile Bay based on official tide gauges. 

Many low-lying coastal roads across the area were impacted from the coastal flooding, including Shell Belt Rd, Coden Belt Rd, Highway 193 Dauphin Island Causeway, north side of the Dog River Bridge on the Dauphin Island Parkway, the east and westbound lanes of the Highway 90 Causeway over Mobile Bay, and parts of the Cochrane Causeway. The image below is a comparison view from the morning and afternoon hours on June 8th from the Causeway over Mobile Bay via the Mobile Traffic social media account (showing the ALGOTraffic website and Alabama Department of Transportation webcam view).

 

 

In the southern portion of Mobile County, water encroached into the yards of homes along the Dog River. On the west end of Dauphin Island in southern Mobile County, sand was pushed onto Bienville Blvd with coastal flooding impacting much of the western end of the island. The last 3 miles of Bienville Blvd on the west end of the island was closed due to the flooding with reports of up to 5 feet of sand covering parts of the road. Parts of the Causeway leading to Dauphin Island were closed at times due to coastal flooding during the event.

Further east, more minor coastal flooding was observed along the Baldwin County coastline and across northwest Florida. Minor coastal flooding occurred along portions of Fort Morgan Rd and along the Fish River in Baldwin County. Large breaking waves also resulted in beach erosion along the immediate coast in Baldwin County. Minor coastal flooding was observed along Bayou Texar and Bayou Grande areas in Escambia County FL with a significant amount of water and sand along portions of Highway 399, particularly in the Fort Pickens and Opal Beach areas. In Okaloosa County, the sea wall at Meigs Park in Shalimar was damaged with minor coastal flooding noted in the area.

Official NOAA/NOS/CO-OPS tide gauges were used to measure the coastal flooding across the area during Tropical Storm Cristobal. Time series plots from several of these NOAA/NOS/CO-OPS tide gauges across coastal Alabama and northwest Florida can be viewed below. (Note: MHHW datum is used as a proxy for inundation above normally dry ground)
