SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Hurricane Warning is in effect for... * Punta Maldonado westward to Zihuatanejo A Hurricane Watch is in effect for... * Lagunas de Chacahua to Punta Maldonado A Tropical Storm Warning is in effect for... * Lagunas de Chacahua to Punta Maldonado A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area, in this case within 12 hours. A Hurricane Watch means that hurricane conditions are possible within the watch area, in this case within the next 12 hours. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. Interests elsewhere in southern and southwestern Mexico should monitor the progress of Otis. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 1000 PM CDT (0300 UTC), the center of Hurricane Otis was located near latitude 16.1 North, longitude 99.7 West. Otis is moving toward the north-northwest near 9 mph (15 km/h), and this general motion is expected through for the next day or so, with landfall forecast overnight or early on Wednesday in southern Mexico. Satellite data indicate that the maximum sustained winds have increased to near 160 mph (260 km/h) with higher gusts. Otis is a category 5 hurricane on the Saffir-Simpson Hurricane Wind Scale. Otis is forecast to remain a category 5 hurricane through landfall, and rapid weakening is then forecast due to the higher terrain of Mexico. Otis will likely dissipate over southern Mexico on Wednesday night. Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 70 miles (110 km). The estimated minimum central pressure is 927 mb (27.38 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Otis can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP3 and WMO header WTPZ43 KNHC and on the web at hurricanes.gov/text/MIATCDEP3.shtml WIND: Hurricane conditions are expected within portions of the hurricane warning area by late tonight and early Wednesday, with extremely destructive winds near the core. Tropical storm conditions are expected to first reach the coast within the warning areas soon, and then spread northwestward within the warning areas through Wednesday. Winds affecting the upper floors of high-rise buildings will be significantly stronger than those near ground level. STORM SURGE: A potentially catastrophic storm surge is expected to produce life-threatening coastal flooding near and to the east of where the center makes landfall. Near the coast, the surge will be accompanied by large and destructive waves. RAINFALL: Otis is expected to produce rainfall totals of 8 to 16 inches with maximum amounts of 20 inches through Thursday across Guerrero and the western coastal sections of Oaxaca. This rainfall will produce flash and urban flooding, along with mudslides in areas of higher terrain. SURF: Swells generated by Otis will affect portions of the southern coast of Mexico during the next couple of days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 100 AM CDT. Next complete advisory at 400 AM CDT. $$ Forecaster Blake

Issued at 1100 PM AST Tue Oct 24 2023 000 WTNT45 KNHC 250239 TCDAT5 Hurricane Tammy Discussion Number 27 NWS National Hurricane Center Miami FL AL202023 1100 PM AST Tue Oct 24 2023 Satellite data indicate Tammy has strengthened tonight. Deep convection has increased near and over the center of the hurricane during the past several hours, resulting in a cold and expanding central dense overcast with intermittent glimpses of a ragged eye. Recent SSMIS and GMI passive microwave images show a tighter inner core compared to earlier today, with a mid-level eyewall that mostly wraps around the center. The subjective Dvorak estimates from SAB and TAFB have risen to T4.5/77 kt and T4.0/65 kt, respectively, with similar increases in the various UW-CIMSS objective estimates. Thus, the initial intensity is raised to 75 kt for this advisory. Despite strengthening upper-level winds over Tammy, increasing upper-level divergence associated with a deep-layer trough over the western Atlantic could support some additional intensification in the near term, as shown by the GFS and some of the regional models. Given recent trends, the updated NHC intensity forecast is raised at 12-24 h to account for this potential. Then, Tammy is expected to merge with a cold front currently analyzed to the northwest of the hurricane. This extratropical transition is forecast to be completed by 36 h, with an expansion of Tammy's wind field as it becomes a hurricane-force extratropical cyclone. Thereafter, the global models show the frontal cyclone weakening through the rest of the period. There is some potential it could shed its frontal structure this weekend, but for now the model-simulated satellite imagery does not show much increase in convection during that time. Tammy is moving northeastward (50 degrees/8 kt) within the flow between a deep-layer trough over the western Atlantic and a subtropical ridge over the central Atlantic. Tammy is expected to turn northward during the next day or so as it becomes captured by the upper trough. The updated NHC forecast lies slightly right of the previous one in the first 24 h, mostly based on the more northeastward initial position. Then, the cyclone is forecast to move more slowly northwestward in 2-3 days within weaker steering currents. The long-range track forecast is highly uncertain, with diverging global and ensemble model solutions that move the shallower cyclone in opposite directions. Given the above-average uncertainty, it seems prudent to make little change to this portion of the track forecast at this time.

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0732 PM CDT Tue Oct 24 2023 Valid 250100Z - 251200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE SOUTHERN HIGH PLAINS... ...SUMMARY... Thunderstorms, associated with marginally severe wind gusts and hail, will continue to be possible this evening over parts of the southern High Plains. ...Southern High Plains... Latest water vapor imagery shows a mid-level low over northwestern Mexico with a plume of mid-level moisture located in southwesterly flow over the southern Rockies. Thunderstorms are ongoing within this plume from eastern Arizona eastward into west Texas, where surface dewpoints are in the lower to mid 60s F. The RAP is analyzing MLCAPE in the 1000 to 1500 J/kg range across much of west-central Texas. As the storms continue to interact with the northwestern edge of the moderately unstable airmass, the instability combined with moderate to strong deep-layer shear, will be likely be sufficient for an isolated severe threat. Hail, along with a few marginally severe wind gusts, will be possible with the stronger cores over the next few hours. ..Broyles.. 10/25/2023 Read more

Corrected order of systems

Active Systems:
The National Hurricane Center is issuing advisories on Hurricane
Otis, located roughly a hundred miles south of the southern coast
of Mexico.

Southwestern East Pacific:
A weak area of low pressure has formed about 1300 miles southwest
of the southern tip of the Baja California peninsula with some
associated shower activity. Upper-level winds could support some

* Formation chance through 5 days...low...20 percent.

South of Central America and Mexico:
A broad area of low pressure is likely to form in a day or two over
the far eastern Pacific, partially related to the remnants of
Atlantic Tropical Depression Twenty-One which are forecast to move
into the region. Environmental conditions should be conducive
for some development of this system, and a tropical depression
could form late this week or this weekend while the low moves
slowly westward to west-northwestward.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...50 percent.

The Congaree River has been running about 2.7 feet, which is slightly above last week’s levels when the river was at its lowest in more than a decade. Some stretches of the river were more affected than others, with rocks being exposed, according to the Congaree Riverkeeper. Low water levels have also provided a great opportunity to pick up trash in areas that would normally be underwater. WLTX-TV Columbia 19 (S.C.), Oct 24, 2023

A farm in New Orleans that grows lettuce, arugula and other leafy greens lost thousands of dollars’ worth of lettuce, but still managed to provide customers with leafy greens. Farm operators watered 22 hours a day, but were going to pull that back to 15 or 16 hours a day. One urban farm spent $1,500 during two weeks in September to increase their irrigation capacity. Another urban farm has delayed communicating about this season’s subscription service due to uncertainty of intense heat and drought. Drought will also determine how much local farms can help with food insecurity in New Orleans. The growing season was getting started in the Greater New Orleans area. Local farmers were already enduring crop loss from drought. Verite News (New Orleans, La.), Oct 11, 2023

Farmers were working to get their crops out of the field, but with a second year of drought slowing navigation on the Mississippi River, grain storage was in short supply. One Arkansas farmer was using grain bags, which are long plastic bags that can be used to contain cereals for a while. The volume of grain shipped on the Mississippi has fallen by half from the average of the past three years, according to the US Department of Agriculture. Yahoo! News/AFP, Oct 23, 2023

The statewide modified burn ban remained in effect, but some parishes have chosen to allow burning again. However, the National Weather Service predicted that ongoing drought and low relative humidity would cause widespread fires across Louisiana. NOLA.com (New Orleans, La.), Oct 22, 2023 The statewide burn ban in Louisiana has been extended by at least a week as fires continued to burn. Outdoor burning was prohibited, but outdoor cooking was permitted. During August, 551 wildfires consumed more than 53,000 acres, although the average acreage burned during the month is 295 acres. Shreveport Times Online (La.), Sept 7, 2023 Louisiana’s previous statewide burn ban, issued Aug. 7, has been replaced with an extended burn ban that prohibited all agricultural burning. The order will remain in effect until rescinded. All private burning was also prohibited also. Attorney General Jeff Landry urged Louisianans to join him in prayer for rain. Lafayette Daily Advertiser (La.), Aug 29, 2023 The State of Louisiana issued a statewide burn ban due to continued heat and drought. The ban will remain in effect until it is rescinded by state officials. WWL-TV (New Orleans, La.), Aug 7, 2023

Issued at 1000 PM CDT Mon Oct 23 2023 000 WTPZ43 KNHC 240239 TCDEP3 Tropical Storm Otis Discussion Number 7 NWS National Hurricane Center Miami FL EP182023 1000 PM CDT Mon Oct 23 2023 Otis has the appearance of a sheared tropical storm this evening, with the center on the eastern edge of a relatively new burst of deep convection. The overall satellite intensity estimates still support an initial wind speed of 45 kt for this advisory. Despite the shear, recent microwave data indicate that Otis has notable low-level structure, with a ring observed in 37 GHz microwave data. While this can be associated with rapid intensification, none of the models show that intensity change occurring, seemingly due to persistent moderate shear and some dry air in the mid-levels. Still, it makes sense to stay on the high side of the guidance given the structure and very warm SSTs in the path. Thus, the new NHC forecast track is similar to the previous one, showing Otis near hurricane strength at landfall between 36-48 hours. Otis continues moving slowly north-northwestward at 6 kt in the flow between a mid- to upper-level trough to its northwest and a ridge to its east. This flow will likely cause the storm to move to the north-northwest or northwest through landfall. While most of the models respond by bringing Otis to the coast of southern Mexico on Wednesday, the GFS model remains an outlier and keeps Otis weaker and offshore. The GFS solution seems very unlikely given the overall synoptic pattern, so the NHC track forecast will put little weight on its solution, keeping the official forecast about the same as the previous one, on the eastern side of the guidance envelope. Key Messages: 1. Heavy rains from Otis will begin to impact areas of southwest Mexico on Tuesday. This rainfall will produce flash and urban flooding, along with mudslides in areas of higher terrain. 2. Tropical storm conditions are expected and hurricane conditions are possible beginning late Tuesday along portions of the southern coast of Mexico, where a Tropical Storm Warning and Hurricane Watch remain in effect.
