SUMMARY OF 800 PM MST...0300 UTC...INFORMATION ---------------------------------------------- LOCATION...18.2N 107.4W ABOUT 210 MI...340 KM WSW OF MANZANILLO MEXICO ABOUT 365 MI...585 KM SSE OF CABO SAN LUCAS MEXICO MAXIMUM SUSTAINED WINDS...115 MPH...185 KM/H PRESENT MOVEMENT...WNW OR 300 DEGREES AT 9 MPH...15 KM/H MINIMUM CENTRAL PRESSURE...962 MB...28.41 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * Punta San Telmo to Playa Perula A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. Interests elsewhere in southwestern Mexico should monitor the progress of Flossie. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 800 PM MST (0300 UTC), the center of Hurricane Flossie was located near latitude 18.2 North, longitude 107.4 West. Flossie is moving toward the west-northwest near 9 mph (15 km/h). A west-northwestward to northwestward motion is anticipated during the next few days. Maximum sustained winds have increased to near 115 mph (185 km/h) with higher gusts. Flossie is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some additional strengthening is possible tonight and Wednesday morning. Later Wednesday, steady to rapid weakening is expected. Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 90 miles (150 km). The estimated minimum central pressure is 962 mb (28.41 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Hurricane Flossie can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP1 and WMO header WTPZ41 KNHC. RAINFALL: Hurricane Flossie should produce additional rainfall totals of 1 to 2 inches, with isolated maximum totals of 3 inches, across coastal portions of the Mexican states of Michoacán, Colima, and Jalisco into Wednesday. This rainfall could lead to localized flash flooding. For a complete depiction of forecast rainfall associated with Hurricane Flossie, please see the National Weather Service Storm Total Rainfall Graphic available at hurricanes.gov/graphics_ep1.shtml?rainqpf WIND: Tropical storm conditions are expected within portions of the warning area for the next few hours. SURF: Swells generated by Flossie will affect portions of the coast of southwestern Mexico, and the Baja California peninsula during the next few 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 1100 PM MST. Next complete advisory at 200 AM MST. $$ Forecaster Bucci NNNN

MD 1538 CONCERNING SEVERE THUNDERSTORM WATCH 482... FOR PORTIONS OF WESTERN SOUTH DAKOTA...WESTERN NEBRASKA...AND EASTERN WYOMING
Mesoscale Discussion 1538 NWS Storm Prediction Center Norman OK 0743 PM CDT Tue Jul 01 2025 Areas affected...portions of western South Dakota...western Nebraska...and eastern Wyoming Concerning...Severe Thunderstorm Watch 482... Valid 020043Z - 020215Z The severe weather threat for Severe Thunderstorm Watch 482 continues. SUMMARY...Strong to severe storms, including a few supercells are ongoing and expected to continue this evening. Large hail and damaging winds are likely to continue. DISCUSSION...Across WW 482, several clusters of severe storms are ongoing and expected to continue this evening. Several supercells have organized across southern SD with reports of hail and damaging gusts. The environment downstream remains favorable for supercells with 2000-2500 J/kg of MLCAPE and 30-40 kt of bulk shear. Hail appears to be the most likely threat given the supercell mode. However, some upscale growth has already been noted, and is expected to continue this evening with consolidating outflows. This would support an increasing risk for damaging winds, given MLCL height of 1700-2000 m and DCAPE of 1500+ J/kg. Additional strong to occasional severe storms may continue across western SD and far southeast MT. With less buoyancy and increasing MLCINH, confidence in a sustained severe risk is lower but hail and damaging gusts remain possible. ..Lyons.. 07/02/2025 ...Please see www.spc.noaa.gov for graphic product...

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0756 PM CDT Tue Jul 01 2025 Valid 020100Z - 021200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE NORTHERN/CENTRAL PLAINS... ...SUMMARY... Scattered severe thunderstorms should continue this evening over parts of the northern/central Plains, with large hail the primary risk. Isolated damaging winds will also remain possible for a couple more hours across portions of the Mid-Atlantic and Southeast. ...Northern/Central Plains... Multiple supercells developed this afternoon/evening across parts of the northern/central High Plains, generally along/east of a surface lee trough. Although low-level flow remains fairly modest per area VWPs, sufficient west-northwesterly mid/upper-level flow will continue to foster around 30-40 kt of deep-layer shear and updraft organization. Persistent supercells will pose mainly a large hail threat as they move slowly south-southeastward for at least the next several hours. An increasing risk for isolated severe winds may also develop given the well-mixed boundary layer and gradual upscale growth anticipated. Reference Mesoscale Discussion 1538 for more details on the short-term severe threat across this region. A separate area of mainly elevated convection may develop later tonight across a broader portion of SD in a low-level warm advection regime. This activity may have an isolated hail threat. ...Mid-Atlantic into the Southeast... Loosely organized convection should continue this evening from parts of the Mid-Atlantic and Southeast along/ahead of a cold front. An isolated threat for damaging winds should persist where pockets of moderate instability remain. But, generally modest deep-layer shear and a gradually stabilizing boundary layer with the loss of daytime heating will likely lead to a gradual reduction in the overall severe threat this evening. ..Gleason.. 07/02/2025 Read more

WW 481 SEVERE TSTM DC DE MD NJ PA VA WV CW 011655Z - 020100Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 481 NWS Storm Prediction Center Norman OK 1255 PM EDT Tue Jul 1 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of District Of Columbia Delaware Maryland New Jersey South-Central and Southeast Pennsylvania Northern and Central Virginia Eastern West Virginia Panhandle Coastal Waters * Effective this Tuesday afternoon and evening from 1255 PM until 900 PM EDT. * Primary threats include... Scattered damaging wind gusts to 70 mph possible SUMMARY...Thunderstorm coverage is expected to increase across the region over the next several hours ahead of a shortwave trough and attendant cold front. The airmass across the region is moist and unstable, with moderate to strong instability anticipated amid continued daytime heating. Vertical shear is modest, with a predominantly outflow-dominant storm mode anticipated. Given the expected updraft strength and ample moisture, some strong water-loaded downdrafts capable of producing wind damaging are possible. The severe thunderstorm watch area is approximately along and 110 statute miles east and west of a line from 40 miles south southeast of Charlottesville VA to 40 miles northwest of Allentown PA. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU1). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes. && AVIATION...A few severe thunderstorms with hail surface and aloft to 1 inch. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 24020. ...Mosier Read more
