Abnormal dryness and moderate to severe drought were reduced in parts of the islands, mainly due to improvements in vegetation from leeward rainfall earlier in July. Drought should be defined in relative terms, i.e. Warmer-than-normal temperatures are likely across the Southwest and along the immediate East Coast, while cooler-than-normal temperatures are likely to dominate from the Plains to Appalachians, in the Pacific Northwest, and across most of Alaska.Download maps for selected areas, compare maps from two different weeks, and request a custom map and more.View tabular data, see a time series, download datasets, and get data in GIS formats.Read the drought summary for the current week or revisit a summary from a prior week.Get contact information for the authors, read the history of the U.S. Drought Monitor, and learn about how drought is classified.See some of the products and tools that are used as part of weekly process.The Drought Monitor summary map identifies general areas of drought and labels them by intensity.
The month-to-date rainfall total at the airport is 130.5% of normal, while YTD is 86.1% of normal. As a result of the uncertainty of the rainfall estimates at the 5km scale derived from a relatively sparse underpinning rain gauge network, it is not recommended that the portal be sole source of any operational analysis.There are many other sources of information for drought monitoring, notably the Hydrological Summaries produced at CEH and the Water Situation Reports produced by the Environment Agency (EA) and similar products developed by Natural Resources Wales (NRW) and the Scottish Environment Protection Agency (SEPA). For this reason, Kapingamarangi drought designation of severe drought was unchanged.This was a dry week for the Marshall Islands, with most stations receiving less than 1 inch of rain. Data is updated at the beginning of each month.

The airport's month-to-date and year-to-date rainfall totals were 76.9% and 77.6% of normal, respectively. This normalises rainfall deficits based on the historic record, meaning the current situation is expressed relative to the past range of variability for the place in question.This means the index can be compared between localities with very different rainfall regimes (comparing, say, a wet catchment in upland Scotland with a dry catchment in low-lying East Anglia), and between times of year.This is particularly important, as droughts occur in all regions, including areas that are generally known for being wet. But little to no rain occurred in a large swath from southwest Texas to western Tennessee and northern Mississippi.
Severe drought disappeared from southwest Montana, but the rain that fell in New Mexico was not enough to improve conditions there. The data within the drought portal are based on the Standardised Precipitation Index (SPI) – an indicator of drought that is widely used internationally for drought monitoring. In future this will be extended to include the impact of varying evaporation rates, as well as drought metrics based on river flow and groundwater conditions. But abnormal dryness or moderate drought expanded in parts of Colorado and the Dakotas, and abnormal dryness and moderate to severe drought expanded in Nebraska. SPI values ranged between abnormally dry to moderate drought in East Hill at all months and drought free to moderate drought for the 1,3,6,9 months, and exceptional drought for the 12-month at the airport. A tropical system is predicted to sideswipe the East Coast, dumping an inch or more of rain across Florida to the Mid-Atlantic states, 3 or more inches over southern Florida, and up to 2 inches over eastern North Carolina and southeast Virginia. Similarly, St. Croix had only 0.36 inch of rain at the Henry E. Rohlsen airport this week, 0.38 inch of rain at the CoCoRaHS station, and 1.10 at the UVI sheep research facility (17.7160N, 64.7958W) reported. Since Fananu has had close to 2 inches or more of rain the last three weeks, Fananu's drought designation was changed to drought free conditions. The Drought Monitor summary map identifies general areas of drought and labels them by intensity. But little to no rain fell in a few areas of Kansas, across parts of Nebraska and Colorado, across even more of the Dakotas, and across most of Wyoming. D1 is the least intense level and D4 the most intense. The UK drought portal is a tool to help visualise the current meteorological conditions across the UK, and understand the severity and magnitude of drought at different spatial scales across the UK over the past half century. tool to help visualise the current meteorological drought status across the UK Definition and comparison with other countries. But the rain was hit or miss, with large areas receiving less than a quarter of an inch. Droughts can be visualised and explored through interactive maps and graphs. D1 is the least intense level and D4 the most intense.
